'Make Atonement for' in the Bible

And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him.

And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make atonement for it.

Why have you not eaten the sin offering in the holy place, seeing it is most holy, and God has given it to you to bear the iniquity of the congregation, to make atonement for them before the LORD?
