Genesis 6:15

6:15 This is how you should make it: The ark is to be 450 feet long, 75 feet wide, and 45 feet high. ¹ 

Genesis 7:20

7:20 The waters rose more than twenty feet ²  above the mountains. ³ 

Genesis 24:28

24:28 The young woman ran and told her mother’s household all about ⁴  these things.

Genesis 6:16

6:16 Make a roof for the ark and finish it, leaving 18 inches ⁵  from the top. ⁶  Put a door in the side of the ark, and make lower, middle, and upper decks.

[6:15]  ¹ tn Heb “300 cubits long, 50 cubits wide, and 30 cubits high.” The standard cubit in the OT is assumed by most authorities to be about 18 inches (45 cm) long.

[7:20]  ² tn Heb “rose fifteen cubits.” Since a cubit is considered by most authorities to be about eighteen inches, this would make the depth 22.5 feet. This figure might give the modern reader a false impression of exactness, however, so in the translation the phrase “fifteen cubits” has been rendered “more than twenty feet.”

[7:20]  ³ tn Heb “the waters prevailed fifteen cubits upward and they covered the mountains.” Obviously, a flood of twenty feet did not cover the mountains; the statement must mean the flood rose about twenty feet above the highest mountain.

[24:28]  ³ tn Heb “according to.”

[6:16]  ⁴ tn Heb “a cubit.”

[6:16]  ⁵ tn Heb “to a cubit you shall finish it from above.” The idea is that Noah was to leave an 18-inch opening from the top for a window for light.
