TSK · Leviticus 16:33

And if thou make me an altar of stone, thou shalt not build it of hewn stones; for if thou lift up thy tool upon it, thou hast polluted it.

And Aaron shall present the bullock of the sin-offering, which is for himself, and shall make atonement for himself, and for his house, and shall kill the bullock of the sin-offering which is for himself:

And he shall go out unto the altar that is before Jehovah, and make atonement for it, and shall take of the blood of the bullock, and of the blood of the goat, and put it upon the horns of the altar round about.

And ye shall do no manner of work in that same day; for it is a day of atonement, to make atonement for you before Jehovah your God.
