Leviticus 4:17-19

Amplified Bible

¹⁷ and the priest shall dip his finger in the blood, and sprinkle it seven times before the Lord, in front of the veil [which screens off the Holy of Holies and the ark of the covenant]. ¹⁸ He shall put some of the blood on the horns of the altar [of incense] which is before the Lord in the Tent of Meeting; and he shall pour out all the rest of the blood at the base of the altar of burnt offering which is at the doorway of the Tent of Meeting. ¹⁹ He shall remove all its fat from the bull and offer it up in smoke on the altar.
