Leviticus 4:12

9 and the two kidneys, and the fat that is on them, which is by the loins, and the cover on the liver, with the kidneys, shall he take away,

10 as it is taken off from the ox of the sacrifice of peace-offerings: and the priest shall burn them on the altar of burnt offering.

11 The skin of the bull, and all its flesh, with its head, and with its legs, and its inwards, and its dung,

12 even the whole bull shall he carry forth outside the camp to 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.

13 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 Yahweh has commanded not to be done, and are guilty;

14 when the sin in which they have sinned is known, then the assembly shall offer a young bull for a sin-offering, and bring it before the tent of meeting.

15 The elders of the congregation shall lay their hands on the head of the bull before Yahweh; and the bull shall be killed before Yahweh.
