Leviticus 1:2, 6, 10

“Give the following instructions to the people of Israel. When you present an animal as an offering to the LORD, you may take it from your herd of cattle or your flock of sheep and goats.

Then skin the animal and cut it into pieces.

“If the animal you present as a burnt offering is from the flock, it may be either a sheep or a goat, but it must be a male with no defects.
