'Make Atonement for' in the Bible

For seven days you shall make atonement for the altar [of burnt offering] and consecrate it; then the altar shall be most holy. Whatever touches the altar must be holy (set apart for God’s service).

The rich shall not give more and the poor shall not give less than half a shekel, when you give this contribution to the Lord to make atonement for yourselves.

You shall take the atonement money from the Israelites and use it [exclusively] for the service of the Tent of Meeting, so that it may be a memorial for the Israelites before the Lord, to make atonement for yourselves.”

Then the next day Moses said to the people, “You have committed a great sin. Now I will go up to the Lord; perhaps I can make atonement for your sin.”
