Genesis 6:13-15

Darby Translation

¹³ And God said to Noah, The end of all flesh is come before me, for the earth is full of violence through them; and behold, I will destroy them with the earth.

¹⁴ Make thyself an ark of gopher wood: [with] cells shalt thou make the ark; and pitch it inside and outside with pitch.

¹⁵ And thus shalt thou make it: let the length of the ark be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.
