Leviticus 9:6

2 He said to Aaron, “Take for yourself a young bull for a sin offering and a ram for a burnt offering, both without blemish, and present them before the LORD.

3 Then speak to the Israelites and say, ‘Take a male goat for a sin offering, a calf and a lamb—both a year old and without blemish—for a burnt offering,

4 an ox and a ram for a peace offering to sacrifice before the LORD, and a grain offering mixed with oil. For today the LORD will appear to you.’”

5 So they took what Moses had commanded to the front of the Tent of Meeting, and the whole congregation drew near and stood before the LORD.

6 And Moses said, “This is what the LORD has commanded you to do, so that the glory of the LORD may appear to you.”

7 Then Moses said to Aaron, “Approach the altar and sacrifice your sin offering and your burnt offering to make atonement for yourself and for the people. And sacrifice the people’s offering to make atonement for them, as the LORD has commanded.”

8 So Aaron approached the altar and slaughtered the calf as a sin offering for himself.

9 The sons of Aaron brought the blood to him, and he dipped his finger in the blood and applied it to the horns of the altar. And he poured out the rest of the blood at the base of the altar.

10 On the altar he burned the fat, the kidneys, and the lobe of the liver from the sin offering, as the LORD had commanded Moses.
