The Basics of Judaism: Sin and Repentance: Animal Sacrifices Atoning for Sin:
Does the Jewish religion require animal sacrifices to atone for sin?
Animal sacrifices, on the Day of Atonement and other occasions, were an
important means of atoning for sin when the Temple existed. But the
principal method of atonement for sin, whether or not the Temple exists,
is repentance. This is clearly stated in the Bible; good sources for it
are 1 Samuel 15:22, Hosea 14:2 and Psalms 32:5.
