Leviticus 4:13-20 (New International Version)

 ¹³ " 'If the whole Israelite community sins unintentionally and does what is forbidden in any of the LORD's commands, even though the community is unaware of the matter, they are guilty. ¹⁴ When they become aware of the sin they committed, the assembly must bring a young bull as a sin offering and present it before the Tent of Meeting. ¹⁵ The elders of the community are to lay their hands on the bull's head before the LORD, and the bull shall be slaughtered before the LORD. ¹⁶ Then the anointed priest is to take some of the bull's blood into the Tent of Meeting. ¹⁷ He shall dip his finger into the blood and sprinkle it before the LORD seven times in front of the curtain. ¹⁸ He is to put some of the blood on the horns of the altar that is before the LORD in the Tent of Meeting. The rest of the blood he shall pour out at the base of the altar of burnt offering at the entrance to the Tent of Meeting. ¹⁹ He shall remove all the fat from it and burn it on the altar, ²⁰ and do with this bull just as he did with the bull for the sin offering. In this way the priest will make atonement for them, and they will be forgiven.
