Leviticus 4:12-15

12even the whole bullock shall he carry forth outside 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 assembly of Israel sin inadvertently, and the thing be hid from the eyes of the congregation, and they do [somewhat against] any of all the commandments of Jehovah [in things] which should not be done, and are guilty;

14and the sin wherewith they have sinned against it have become known; then the congregation shall present a young bullock for the sin-offering, and shall bring it before the tent of meeting;

15and the elders of the assembly shall lay their hands on the head of the bullock before Jehovah; and one shall slaughter the bullock before Jehovah.
