And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.

What does Genesis 6:15 mean?

Genesis 6:15 gives the precise measurements God told Noah to use when building the ark: 300 cubits long, 50 cubits wide, and 30 cubits high. This verse shows that the ark was to be a very large, rectangular vessel, built according to specific instructions.

In this verse, God is speaking directly to Noah, giving him detailed directions for constructing the ark as a means of surviving the coming flood. The use of exact dimensions highlights the seriousness and intentionality of God's instructions, emphasizing that Noah was not to build the ark however he pleased, but according to a clear plan.

The Hebrew behind Genesis 6:15

  • "ark" (תֵּבָה, teivah): This word refers to a box or chest, not a typical boat. It suggests the ark was designed more for floating and preserving life than for navigation.
  • "cubit" (אַמָּה, ammah): A cubit was an ancient unit of length, often understood as the distance from the elbow to the tip of the middle finger (roughly 18 inches or 45 centimeters). This gives a sense of just how massive the ark was.
  • "length" (אֹרֶךְ, orekh), "breadth" (רֹחַב, rokhav), "height" (קוֹמָה, qomah): These words show that the description is about the ark’s physical dimensions, emphasizing its size and shape rather than its appearance or decoration.

Why Genesis 6:15 matters

  • This verse clears up the common misconception that the ark was a small boat; the measurements show it was a huge structure, more like a floating building.
  • The focus on specific dimensions highlights that Noah’s obedience involved following God’s instructions exactly, not improvising or guessing.
  • By giving these details, Genesis 6:15 connects the story to the real world, inviting readers to picture the ark as a tangible, physical object rather than just a symbol or legend.
