Leviticus 8:13-15

Complete Jewish Bible

¹³ Moshe brought Aharon’s sons, clothed them with tunics, wrapped sashes on them and put headgear on them, as Adonai had ordered Moshe.

(v) ¹⁴ Then the young bull for the sin offering was brought, and Aharon and his sons laid their hands on the head of the bull for the sin offering. ¹⁵ After it had been slaughtered, Moshe took the blood and put it on the horns of the altar all the way around with his finger, thus purifying the altar. The remaining blood he poured out at the base of the altar and consecrated it, to make atonement for it.
