15 "The top part is where the sacrifices are burned. It is seven feet high. A horn sticks out from each of its upper four corners.
16 The top part of the altar is square. It is 21 feet long and 21 feet wide.
17 The middle part is also square. It is 24 and a half feet long. It is 24 and a half feet wide. Its rim is ten and a half inches wide. The base of the altar is 21 inches high all the way around. The steps leading up to the top of the altar face east."
18 Then the man said to me, "Son of man, the Lord and King speaks. He says, 'Here are the rules for the altar when it is built. Follow them when you sacrifice burnt offerings and sprinkle blood on it.
19 Give a young bull to the priests as a sin offering. They are Levites from the family of Zadok. They approach me to serve me,' announces the Lord and King.
20 'Get some of the bull's blood. Put it on the four horns. Also put it on the four corners of the middle part of the altar and all around the rim. That will make the altar pure and clean.
21 Use the bull for the sin offering. Burn it in the proper place outside the temple.
