Leviticus 4:5-7

5Then the 1anointed priest is to take some of the blood of the bull and bring it to the tent of meeting,

6and the priest shall dip his finger in the blood and sprinkle some of the blood seven times before the Lord, in front of 2the veil of the sanctuary.

7The priest shall also put some of the blood on the horns of 3the altar of fragrant incense which is before the Lord in the tent of meeting; and all the rest of the blood of the bull he shall pour out at the base of the altar of burnt offering, which is at the doorway of the tent of meeting.
