Leviticus 4:1

2 Speak unto 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 do against any of them:

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

4 And he shall bring the bullock unto the door of the tabernacle of the congregation before the LORD; and shall lay his hand upon the bullock's head, and kill the bullock before the LORD.

5 And the priest that is anointed shall take of the bullock's blood, and bring it to the tabernacle of the congregation:

6 And the priest shall dip his finger in the blood, and sprinkle of the blood seven times before the LORD, before the vail of the sanctuary.

7 And the priest shall put some of the blood upon the horns of the altar of sweet incense before the LORD, which is in the tabernacle of the congregation; and shall pour all the blood of the bullock at the bottom of the altar of the burnt offering, which is at the door of the tabernacle of the congregation.
