Leviticus 1:2, 6, 10

“Speak to the Israelites and say to them: ‘When anyone among you brings an offering to the LORD, bring as your offering an animal from either the herd or the flock.

You are to skin the burnt offering and cut it into pieces.

“ ‘If the offering is a burnt offering from the flock, from either the sheep or the goats, you are to offer a male without defect.
