What is a Cubit in the Bible?
Quick Summary
A cubit in the Bible is an ancient unit of measurement based on the length of the forearm from elbow to fingertip. In Scripture it usually refers to a length between seventeen and twenty twenty one inches, depending on the culture and period. The cubit is used throughout the Old and New Testaments to describe the dimensions of sacred spaces, large structures, and significant objects.
Introduction
Ancient people measured the world with their bodies. The cubit is one of the oldest and most widely used measurements in the Bible. While the term may feel unfamiliar to modern readers, it was a practical everyday standard in the ancient Near East. When biblical writers describe arks, altars, temples, and walls, they rely on cubits to convey size and significance.
Understanding the cubit helps modern readers picture the scale of well known stories such as Noah building the ark in Genesis 6:15 or the measurements of Solomon's Temple in 1 Kings 6:2. A cubit also appears in narratives involving Goliath, the Tabernacle, Ezekiel's visionary temple, and the rebuilding efforts after the exile. It was a flexible but consistent way for ancient writers to express height, width, and depth.
What Is a Cubit?
The word "cubit" comes from the Latin cubitus which refers to the forearm. In the ancient world this distance from elbow to fingertip served as the basic reference point for construction, trade, and craftsmanship. Because peoples' bodies differ, some variation existed in cubit length across regions and cultures.
Archaeological evidence from Egyptian and Mesopotamian measuring rods shows a common pattern. The standard cubit was around seventeen to eighteen inches. Some cultures also used an extended or royal cubit which added the breadth of a hand making it approximately twenty or twenty one inches.
Biblical references typically assume this range. Scholars often calculate measurements in the Hebrew Scriptures using a standard cubit of about seventeen and a half inches, though some passages suggest the longer version. Understanding this range helps readers translate ancient scale into modern terms.
Cubits in Key Biblical Stories
Noah's Ark
Genesis 6:15 uses cubits to describe the vessel's dimensions. The ark measured three hundred cubits long, fifty cubits wide, and thirty cubits high. Even at the shorter end of the cubit range this yields a massive structure. Ancient readers would have understood immediately the impressive scale.
The Tabernacle
The portable sanctuary described in Exodus relies heavily on cubits. Moses receives detailed instructions for frames, curtains, altars, and furnishings. For instance, the Ark of the Covenant in Exodus 25:10 is two and a half cubits long, one and a half wide, and one and a half high. These instructions emphasize both beauty and precision.
Goliath's Height
In 1 Samuel 17:4 Goliath is described as "six cubits and a span" tall. This measurement places him well over nine feet when using the long cubit. The phrase signals not only height but symbolic power in the narrative.
Solomon's Temple
The construction of the temple in Jerusalem is measured in cubits. First Kings 6:2 records that the building was sixty cubits long, twenty cubits wide, and thirty cubits high. The cubit shapes the entire architectural description helping the reader visualize sacred space.
Ezekiel's Visionary Temple
Ezekiel 40:5 notes a "measuring reed of six long cubits." This passage reveals the existence of a specific long cubit used for visionary precision. The prophet's vision of restored worship is presented with mathematical care.
Why Cubits Matter for Biblical Interpretation
The cubit grounds many biblical passages in physical reality. By translating these measurements into modern terms readers gain a better sense of scale. This clarity enriches devotional reading and supports deeper study.
The cubit also highlights the Bible's rootedness in ancient culture. Understanding this measurement draws us closer to the world of the text. It helps modern readers appreciate the craftsmanship of ancient builders and the grandeur of structures meant for worship.
FAQs
How long is a cubit in modern terms?
A common estimate places the standard cubit at about seventeen and a half inches. The long or royal cubit is around twenty to twenty one inches.
Why do cubits vary?
Measurements tied to body parts naturally vary across cultures. Egyptian, Babylonian, and Hebrew cubits all fall within similar ranges but differ slightly depending on historical era.
Did people actually use their arms to measure things?
Yes. Body based measurements were practical before standardized tools became common. Craftsmen used their arms, hands, and fingers to maintain consistency.
Does the New Testament use cubits?
The New Testament mentions cubits occasionally, as in Matthew 6:27 and Luke 12:25. These references highlight human limitations rather than architectural size.
How should modern readers convert cubits?
Using seventeen to eighteen inches for general calculation works well. When precision matters or when the text suggests a royal cubit, twenty to twenty one inches is a better estimate.
