(in traditional or ancient Judaism) an offering made as an atonement for sin.
‘Twice over in the law of the sin-offering, God said to Israel, ‘the sin-offering is most holy’.’
‘There was a ram for a burnt offering, and two young goats for a sin-offering.’
‘Maccoby contends that, where the sin-offering is concerned, the atonement relates more easily to the sin of the offerer, rather than the defilement of the altar.’
‘Jacob cried aloud, putting both hands on the goat: ‘A sin-offering unto the Lord.’’
