“He shall put some of the blood on the horns of the altar which is before Yahweh, that is in the Tent of Meeting; and the rest of the blood he shall pour out at the base of the altar of burnt offering, which is at the door of the Tent of Meeting.”
Leviticus 4:18 (WEB)
Context Reading
16The anointed priest shall bring some of the blood of the bull to the Tent of Meeting. 17The priest shall dip his finger in the blood and sprinkle it seven times before Yahweh, before the veil. 18He shall put some of the blood on the horns of the altar which is before Yahweh, that is in the Tent of Meeting; and the rest of the blood he shall pour out at the base of the altar of burnt offering, which is at the door of the Tent of Meeting. 19All its fat he shall take from it, and burn it on the altar. 20He shall do this with the bull; as he did with the bull of the sin offering, so he shall do with this; and the priest shall make atonement for them, and they shall be forgiven.
