Genesis 6:15
Berean Standard Bible
And this is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide, and 30 cubits high.*
Context
13Then God said to Noah, “The end of all living creatures has come before Me, because through them the earth is full of violence. Now behold, I will destroy both them and the earth. 14Make for yourself an ark of gopher wood;* make rooms in the ark and coat it with pitch inside and out. 15And this is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide, and 30 cubits high.* 16You are to make a roof * for the ark, finish its walls a cubit from the top,* place a door in the side of the ark, and build lower, middle, and upper decks. 17And behold, I will bring floodwaters upon the earth to destroy every creature under the heavens that has the breath of life. Everything on the earth will perish.
