Leviticus 4:12-15

12Even the whole bull shall he carry forth outside the camp to a clean place, where the ashes are poured out, and burn him on the wood with fire: where the ashes are poured out shall he be burnt.12

13And if the whole congregation of Israel shall sin through ignorance, and the thing be hid from the eyes of the assembly, and they have done somewhat against any of the commandments of the LORD concerning things which should not be done, and are guilty; 14When the sin, which they have sinned against it, is known, then the congregation shall offer a young bull for the sin, and bring him before the tabernacle of the congregation. 15And the elders of the congregation shall lay their hands upon the head of the bull before the LORD: and the bull shall be killed before the LORD.
