Leviticus 4:12-15

12even the whole bullock shall he carry forth without the camp unto a clean place, where the ashes are poured out, and burn it on wood with fire: where the ashes are poured out shall it be burnt.

13And if the whole congregation of Israel shall err, and the thing be hid from the eyes of the assembly, and they have done any of the things which the LORD hath commanded not to be done, and are guilty;

14when 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.

15And the elders of the congregation shall lay their hands upon the head of the bullock before the LORD: and the bullock shall be killed before the LORD.
