¹⁹ The priest will take blood from this sin offering and put it on the doorposts of the Temple, the four corners of the upper ledge of the altar, and the gateposts at the entrance to the inner courtyard.

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.

¹⁴ From the gutter the altar rises 3 1⁄2 feet^[a] to a lower ledge that surrounds the altar and is 21 inches^[b] wide. From the lower ledge the altar rises 7 feet^[c] to the upper ledge that is also 21 inches wide.

¹⁸ “Then Aaron will come out to purify the altar that stands before the Lord. He will do this by taking some of the blood from the bull and the goat and putting it on each of the horns of the altar. ¹⁹ Then he must sprinkle the blood with his finger seven times over the altar. In this way, he will cleanse it from Israel’s defilement and make it holy.

²⁰ “When Aaron has finished purifying the Most Holy Place and the Tabernacle and the altar, he must present the live goat.

¹⁷ The upper ledge also forms a square, measuring 24 1⁄2 feet by 24 1⁄2 feet,^[a] with a 21-inch gutter and a 10 1⁄2-inch curb^[b] all around the edge. There are steps going up the east side of the altar.”
