15 and the altar hearth, 7 feet, and from the altar hearth four horns projecting upward.
16 Now the altar hearth is a perfect square, 21 feet long and 21 feet wide.
17 The ledge is 24½ feet long and 24½ feet wide on four sides; the border around it is 10½ inches, and its surrounding base 1¾ feet. Its steps face east.”
18 Then he said to me: “Son of man, this is what the sovereign Lord says: These are the statutes of the altar: On the day it is built to offer up burnt offerings on it and to sprinkle blood on it,
19 you will give a young bull for a sin offering to the Levitical priests who are descended from Zadok, who approach me to minister to me, declares the sovereign Lord.
20 You will take some of its blood, and place it on the four horns of the altar, on the four corners of the ledge, and on the border all around; you will cleanse it and make atonement for it.
21 You will also take the bull for the sin offering, and it will be burned in the appointed place in the temple, outside the sanctuary.
