Leviticus 4:4-7

4He shall bring the bull to the door of the tabernacle of meeting before the Lord, lay his hand on the bull’s head, and kill the bull before the Lord.

5Then the anointed priest shall take some of the bull’s blood and bring it to the tabernacle of meeting.

6The priest shall dip his finger in the blood and sprinkle some of the blood seven times before the Lord, in front of the veil of the sanctuary.

7And the priest shall put some of the blood on the horns of the altar of sweet incense before the Lord, which is in the tabernacle of meeting; and he shall pour the remaining blood of the bull at the base of the altar of the burnt offering, which is at the door of the tabernacle of meeting.
