Leviticus 4:13-20

“If the entire Israelite community sins by violating one of the LORD’s commands, but the people don’t realize it, they are still guilty. When they become aware of their sin, the people must bring a young bull as an offering for their sin and present it before the Tabernacle. The elders of the community must then lay their hands on the bull’s head and slaughter it before the LORD. The high priest will then take some of the bull’s blood into the Tabernacle, dip his finger in the blood, and sprinkle it seven times before the LORD in front of the inner curtain. He will then put some of the blood on the horns of the altar for fragrant incense that stands in the LORD’s presence inside the Tabernacle. He will pour out the rest of the blood at the base of the altar for burnt offerings at the entrance of the Tabernacle. Then the priest must remove all the animal’s fat and burn it on the altar, just as he does with the bull offered as a sin offering for the high priest. Through this process, the priest will purify the people, making them right with the LORD, and they will be forgiven.
