Leviticus 9:3, 15

And to the children of Israel you shall speak, saying, ‘Take a kid of the goats as a sin offering, and a calf and a lamb, both of the first year, without blemish, as a burnt offering

Then he brought the people’s offering, and took the goat, which was the sin offering for the people, and killed it and offered it for sin, like the first one.
