'Make Atonement for' in the Bible

For a seven day period they are to make atonement for the altar, purifying it and consecrating it.

The sheep quota is to be one from each flock of 200 taken from the pastures of Israel. From all of these you are to present grain offerings, burnt offerings, and peace offerings, to make atonement for them," declares the Lord GOD.

The Regent Prince is to provide the burnt offerings, grain offerings, and drink offerings at the festivals, on the New Moons and Sabbaths, and at all of the prescribed festivals of the house of Israel. He is to provide the grain offerings, burnt offerings, and peace offerings in order to make atonement for the house of Israel."

You are also to do this on the seventh day of the month, to make atonement for any person who wanders away or who sins through ignorance in order to make atonement for the Temple.
