'Atoning' in the Bible

“When he finishes atoning for the holy place and the tent of meeting and the altar, he shall offer the live goat.

whom God set forth to be an atoning sacrifice, through faith in his blood, for a demonstration of his righteousness through the passing over of prior sins, in God's forbearance;

It is he who is the atoning sacrifice for our sins, and not for ours only, but also for the whole world's.

This is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins.
