Leviticus 1:2-4

2“Speak to the Israelites and tell them, ‘When someone among you presents an offering to the Lord, you must present your offering from the domesticated animals, either from the herd or from the flock.

3“‘If his offering is a burnt offering from the herd he must present it as a flawless male; he must present it at the entrance of the Meeting Tent for its acceptance before the Lord.

4He must lay his hand on the head of the burnt offering, and it will be accepted for him to make atonement on his behalf.
