'Atonement' in the Bible

And thou shalt take of its blood, and put it on the four horns thereof, and on the four corners of the settle, and upon the border round about: so shalt thou purge and make atonement for it.

Seven days shall they make atonement for the altar and purify it, and consecrate it.

and one lamb out of the flock, out of two hundred, from the well-watered pastures of Israel; for an oblation, and for a burnt-offering, and for peace-offerings, to make atonement for them, saith the Lord Jehovah.

And it shall be the prince's part to supply the burnt-offerings, and the oblation, and the drink-offering, at the feasts, and at the new moons, and on the sabbaths, in all the solemnities of the house of Israel: it is he that shall prepare the sin-offering, and the oblation, and the burnt-offering, and the peace-offerings, to make atonement for the house of Israel.

So thou shalt do also on the seventh of the month for every one that erreth, and for the simple; and ye shall make atonement for the house.
