Leviticus 4
13 Ref And if the whole congregation of Israel err, and the thing be hid from the eyes of the assembly, and they have done any of the things which Jehovah hath commanded not to be done, and are guilty;
14 Ref when the sin wherein they have sinned is known, then the assembly shall offer a young bullock for a sin-offering, and bring it before the tent of meeting.
15 Ref And the elders of the congregation shall lay their hands upon the head of the bullock before Jehovah; and the bullock shall be killed before Jehovah.
