Leviticus 4:6-7

⁶and the priest hath dipped his finger in the blood, and sprinkled of the blood seven times before Jehovah, at the front of the vail of the sanctuary;

⁷and the priest hath put of the blood on the horns of the altar of spice-perfume before Jehovah, which is in the tent of meeting, and all the blood of the bullock he doth pour out at the foundation of the altar of the burnt-offering, which is at the opening of the tent of meeting.
