Parallel
Ezekiel 43:20
Brenton's English Septuagint · Berean Standard Bible
And they shall take of its blood, and shall put [it] on the four horns of the altar, and upon the four corners of the propitiatory, and upon the base round about, and they shall make atonement for it.
You are to take some of its blood and put it on the four horns of the altar, on the four corners of the ledge, and all around the rim; thus you will cleanse the altar and make atonement for it.
