¶ But Aaron and his sons offered upon the altar of the burnt offering, and on the altar of incense, and were appointed for all the work of the place most holy, and to make an atonement for Israel, according to all that Moses the servant of God had commanded.
And thou shalt make an altar of shittim wood, five cubits long, and five cubits broad; the altar shall be foursquare: and the height thereof shall be three cubits.
And Aaron shall make an atonement upon the horns of it once in a year with the blood of the sin offering of atonements: once in the year shall he make atonement upon it throughout your generations: it is most holy unto the Lord.
