Leviticus 4:5-7

5And the priest that is anointed shall take of the bullock's blood, and bring it into the tent of meeting;

6and the priest shall dip his finger in the blood, and sprinkle of the blood seven times before Jehovah before the veil of the sanctuary;

7and the priest shall put of the blood on the horns of the altar of fragrant incense, which is in the tent of meeting, before Jehovah; and he shall pour all the blood of the bullock at the bottom of the altar of burnt-offering, which is at the entrance of the tent of meeting.
