Genesis 7:2-4

Young's Literal Translation

² of all the clean beasts thou dost take to thee seven pairs, a male and its female; and of the beasts which are not clean two, a male and its female;

³ also, of fowl of the heavens seven pairs, a male and a female, to keep alive seed on the face of all the earth;

⁴ for after other seven days I am sending rain on the earth forty days and forty nights, and have wiped away all the substance that I have made from off the face of the ground.'
