Leviticus 4:6-7

MLV(i) 6 And the priest will dip his finger in the blood and sprinkle of the blood seven times before Jehovah, before the veil of the sanctuary. 7 And the priest will put of the blood upon the horns of the altar of sweet incense before Jehovah, which is in the tent of meeting and all the blood of the bullock he will pour out at the base of the altar of burnt offering, which is at the door of the tent of meeting.
