Leviticus 4:14

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.

16 The anointed priest shall bring of the blood of the bull to the tent of meeting:

17 and the priest shall dip his finger in the blood, and sprinkle it seven times before Yahweh, before the veil.
