4 Bible Verses about Atonement, in OT

But [only] once a year the head priest goes alone into the inner room [i.e., Holy of Holies], and never without [animal] blood, which he offers [as a sacrifice] for himself and for the sins done in ignorance by the people.

And, according to the law of Moses, almost everything is [ceremonially] cleansed by blood, for there is no forgiveness [of sins] apart from the shedding of blood.

For every head priest is chosen from among men, and is appointed on behalf of people, to offer both gifts and sacrifices for sins. He is able to gently put up with ignorant and wayward people because he himself is subject to [the same spiritual] weaknesses. And because of this he is obligated to offer [sacrifices] for his own sins also, as well as the people's sins.
