'Propitiation' in the Bible

whom God set forth to be a propitiation, through faith, in his blood, to show his righteousness because of the passing over of the sins done aforetime, in the forbearance of God;

Wherefore it behooved him in all things to be made like unto his brethren, that he might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.

and he is the propitiation for our sins; and not for ours only, but also for the whole world.

Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
