Leviticus 4:16

13 And if the whole congregation of Israel 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;

14 When the sin, which they have sinned against it, is known, then the congregation shall offer a young bullock for the sin, and bring him before the tabernacle of the congregation.

15 And 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.

16 And the priest that is anointed shall bring of the bullock’s blood to the tabernacle of the congregation:

17 And the priest shall dip his finger [in some] of the blood, and sprinkle [it] seven times before the LORD, [even] before the vail.

18 And he shall put [some] of the blood upon the horns of the altar which [is] before the LORD, that [is] in the tabernacle of the congregation, and shall pour out all the blood at the bottom of the altar of the burnt offering, which [is at] the door of the tabernacle of the congregation.

19 And he shall take all his fat from him, and burn [it] upon the altar.
