Leviticus 4:1-4

1And the LORD spoke to Moses, saying,

2Speak to the children of Israel, saying, If a soul shall sin through ignorance against any of the commandments of the LORD concerning things which ought not to be done, and shall break any of them:

3If the priest that is anointed shall sin according to the sin of the people; then let him bring for his sin, which he hath sinned, a young bull without blemish to the LORD for a sin offering.

4And he shall bring the bull to the door of the tabernacle of the congregation before the LORD; and shall lay his hand upon the bull’s head, and kill the bull before the LORD.
