Leviticus 1:1-3

1The Lord called to Moses from the Tabernacle and said to him,

2“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.

3“If the animal you present as a burnt offering is from the herd, it must be a male with no defects. Bring it to the entrance of the Tabernacle so you may be accepted by the Lord.
