The mysteries of Scripture

11 things you might not know about the Bible

The Bible, the Tanakh, the Holy Scriptures, the Word of God: there are many names for this millennial text, but do they all refer to the same thing? Under the name ‘Bible’ —from the Greek biblia, ‘books’— we find different texts, some longer than others, connected to different faiths and traditions. What makes up the Bible? How does it vary from tradition to tradition? What was its original language? Keep on reading to find out the answer to these questions and other interesting facts about this sacred text.

While many people mistakenly refer to the Torah as the "Jewish Bible", it actually includes only the first five books of Moses—what, in Christian tradition, is sometimes called the Pentateuch. The complete collection of sacred Jewish texts is actually called Tanakh, an acronym of the sections included: Torah —the narrations and law written in the books of Moses—, Nevi’im —the Prophets—, and Ketuvim —writings of wisdom and poetic literature.

Are the Jewish Tanakh and the Christian Old Testament the same text? Not quite. Most of the text coincides, but is organized in a different way and translated from different sources. Additionally, books that are not part of the Jewish tradition—for example, Tobit or Judith—are not included in all Christian Bibles.

You might be surprised to learn that not all Christians read the same Bible. While the New Testament is the same, there are differences in what books are included in the Old Testament. Seven books—Tobit, Judith, Wisdom, Sirach, Baruch, and 1 & 2 Maccabees, plus some sections in Daniel and Esther— are considered part of the canon by Catholics and Orthodox traditions, but are not accepted by denominations of Protestant tradition.

Why are these books questioned? They were written at a later time than the rest of the Old Testament, around the 3rd century BCE, and were often only accessible through Greek translations. While Catholics and Orthodox have traditionally accepted them, the Protestant denominations do not, on account of their not being accepted as canonical by the Jewish tradition. However, these texts are often read as historical documents, even if they are not considered to be inspired by God.

The Bible was written across many centuries in different places, so the original text is not in a single language. The majority of the Tanakh and the Old Testament was originally written in Biblical Hebrew (which is different, although related, from Modern Hebrew), while some sections were written in Aramaic.

What about the New Testament? While most writers spoke Aramaic, the text is written in Koine Greek, a colloquial version of Greek used as a common tongue at the time. However, the text still includes words and phrases in Hebrew and Aramaic, such as amen, Abba, or hosanna.

As a text composed by many people across many centuries, the Bible was not penned in a single location, but across three different continents and several countries. The majority of the Tanakh/Old Testament was written in the ancient kingdoms of Israel and Judah, with some parts written during the Israelite exile in Babylon (modern-day Iraq). Additionally, some traditions believe that the books of Moses were written in modern-day Egypt.

What about the New Testament? Though closer in time, its sections were written in places all around the Mediterranean, mainly in ancient Judea, Greece, Macedonia, modern-day Turkey, and Rome.

The Bible is an anthology, written and compiled over several centuries and under different circumstances. As such, it includes a variety of known literary genres, such as historical narratives —for example, Genesis or Acts—, compendiums of law —Leviticus or Deuteronomy—, wisdom literature —Proverbs—, poetry —Psalms or Song of Solomon—, prophetic and apocalyptic texts —Isaiah, Jeremiah, or Revelations—, and letters —Romans or Corinthians.

In addition to all these genres, already established when the sections of the Bible were written, some books include the first recorded examples of a literary genre, such as the Gospels —a unique mix of narrative, biography, and theology—, or the Parables, which, unlike fables, convey complex moral and religious teachings alongside their interpretation.

All Bibles start in the same moment, the beginning of time, but not all Bibles follow the same chronology. The Tanakh narrates the story of the Israelites up until the construction of the Second Temple (6th century BCE), and the New Testament picks the story up around the years 5 to 1 BCE. What happened in the meantime? It depends on who you ask.

In the Protestant traditions, that gap is known as the "Silent Years", on account of the lack of inspired texts and prophets. In the Catholic and Orthodox traditions, the gap is shortened by Maccabees 1 and 2, which narrate the uprising against the Seleucid Empire in the 2nd Century BCE. There is, however, another biblical gap in the New Testament, known as the "Lost Years", that goes from the last mention of Jesus as a child —his visit to the Temple at 12 years old— to his baptism in the River Jordan at 30 years old.

If someone were to ask how many commandments are in the Bible, many would quickly respond that there are 10. However, not all traditions would accept this as a correct answer. The Jewish tradition recognizes 613 divine commandments or mitzvot. The first 10, listed twice in the Torah, are a list of fundamental moral and theological principles, while the remaining 603 regulate different aspects of life, such as society, rituals, ethics, or justice.

Do all Christian traditions follow the same commandments? Yes and no. The text of the Old Testament describes the ten commandments, but does not enumerate them, so each tradition has its own way of assigning numbers to each commandment, which can lead to confusion.

The biblical text is traditionally divided into books, which are divided into verses, but these divisions vary between the Tanakh and the Christian Bibles. The Tanakh contains 24 books divided into 3 sections—Torah, Nevi’im, and Ketuvim. The longest book is Tehillim or Psalms, while the shortest is the book of Obadiah.

In the Christian tradition, the longest book is Jeremiah, while the shortest book is John 3, with only 13 verses. The longest verse (in English) is Esther 8:9 with more than 70 words, while the shortest is John 11:35, with just two.

Have you ever wondered why there are many different depictions of Jesus around the world, even when they are most likely historically incorrect? The truth is, we can only guess what he looked like, based on the historical time and the geographical location, but we don’t have any physical description of him.

The four Gospels give us all sorts of information about Jesus, from his genealogy to his life, his family, his teachings, and his mission, but he is never described in terms of appearance. Even when different people talk about him, he is described based on his place of origin, his lineage, or his actions.

If you have ever read any part of the Bible, you might have noticed that many phrases are repeated. This is not a coincidence, but a deliberate literary device, intended to emphasize certain ideas and help to retain their message.

What is the most repeated phrase in the Bible? Both the Tanakh and the Christian Bibles coincide here, with the phrase "Do not fear" —and similar variants such as "Fear not" or "Be not afraid"— repeated more than 70 times in the Tanakh, and more than a hundred times in the Christian Bible.

Names carry a deep meaning in the Bible, often related to historical circumstances, spiritual characteristics, or prophetic messages. In fact, many passages involve the renaming of individuals to reflect a newfound mission or experience, such as God renaming Abram (‘exalted father’) as Abraham (‘father of a multitude’), or Jesus renaming Simon as Peter (in Aramaic, Kepha, "stone") to mean he would be the rock of early Christianity.

Among these names, one stands out due to its length and its ominous message. In the book of Isaiah, God instructs the prophet Isaiah to name his second child Mahershalalhashbaz, a name that means ‘swift are the spoils, speedy is the plunder’, and is interpreted as prophecising the upcoming invasion of Israel by the Assyrian empire. Fun fact: if this name rings a bell for you, it might be due to the actor Mahershala Ali, whose real name is Mahershalalhashbaz Gilmore.

Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
