'Offering for Sin' in the Bible

Yet the LORD was pleased to crush him and make him ill. When you make his soul an offering for sin, he shall see his offspring. He shall prolong his days, and the pleasure of the LORD shall prosper in his hand.

Now where remission of these is, there is no more offering for sin.

For the bodies of those animals, whose blood is brought into the holy place by the high priest as an offering for sin, are burned outside of the camp.
