Genesis 6:18-20 ▼

18 And I have established My covenant with you, and you have come into the Ark—you, and your sons, and your wife, and your son’s wives with you;

19 and of all that lives, of all flesh, you bring two from every [kind] into the Ark, to keep alive with you; they are male and female.

20 From the bird after its kind, and from the livestock after its kind, [and] from every creeping thing of the ground after its kind, two of every [kind] they come to you, to keep alive.
