Leviticus 1:2-3, 10

“Speak to the children of Israel, and say to them: ‘When any one of you brings an offering to the LORD, you shall bring your offering of the livestock—of the herd and of the flock. ‘If his offering is a burnt sacrifice of the herd, let him offer a male without blemish; he shall offer it of his own free will at the door of the tabernacle of meeting before the LORD.

‘If his offering is of the flocks—of the sheep or of the goats—as a burnt sacrifice, he shall bring a male without blemish.
