Ezequiel 43:20

20 You are to take some of its blood and put it on the four horns of the altar and on the four corners of the upper ledge and all around the rim, and so purify the altar and make atonement for it.

20 And thou shalt take of the blood thereof, and put it on the four horns of it, and on the four corners of the ledge, and upon the border round about: thus shalt thou cleanse it and make atonement for it.
