'Sin offerings' in the Bible

It is not to be cooked with leaven. I have given it to them as their part of the offerings made by fire to me; it is most holy, as are the sin-offerings and the offerings for error.

The money of the offerings for error and the sin-offerings was not taken into the house of the Lord; it was the priests'.

For the holy bread, and for the regular meal offering and the regular burned offering on the Sabbaths and at the new moon and the fixed feasts, and for the sin-offerings to take away the sin of Israel, and for all the work of the house of our God.

You had no desire for offerings of beasts or fruits of the earth; ears you made for me: for burned offerings and sin offerings you made no request.

And being feeble, he has to make sin-offerings for himself as well as for the people.
