15 The top of the altar, the hearth, rises another 7 feet higher, with a horn rising up from each of the four corners.
16 The top of the altar is square, measuring 21 feet by 21 feet.
17 The upper ledge also forms a square, measuring 241/2 feet by 241/2 feet, with a 21-inch gutter and a 101/2-inch curb all around the edge. There are steps going up the east side of the altar.”
18 Then he said to me, “Son of man, this is what the Sovereign lord says: These will be the regulations for the burning of offerings and the sprinkling of blood when the altar is built.
19 At that time, the Levitical priests of the family of Zadok, who minister before me, are to be given a young bull for a sin offering, says the Sovereign lord.
20 You will take some of its blood and smear it on the four horns of the altar, the four corners of the upper ledge, and the curb that runs around that ledge. This will cleanse and make atonement for the altar.
21 Then take the young bull for the sin offering and burn it at the appointed place outside the Temple area.
