Genesis 6:19-22 ESV
And of every living thing of all flesh, you shall bring two of every sort into the ark to keep them alive with you. They shall be male and female. Of the birds according to their kinds, and of the animals according to their kinds, of every creeping thing of the ground, according to its kind, two of every sort shall come in to you to keep them alive. Also take with you every sort of food that is eaten, and store it up. It shall serve as food for you and for them.” Noah did this; he did all that God commanded him.
