Leviticus 4:27-28

²⁷And if one of the people of the land inadvertently sin in doing contrary to any of the commandments of the Lord what is not right to do, and become guilty;

²⁸When his sin is known to him, in what he hath sinned, he shall bring his oblation, a female kid of the goats, unblemished, for the sin that he hath sinned.
