Leviticus 23:18-19

18With the bread, all the people must bring seven perfect sheep. They must be males, each one year old. They must bring a bull. They must also bring two older male sheep. The priest will burn the grain and the animals as a gift to the Lord. The smell of them while they are burning will give the Lord pleasure.

19The priest must sacrifice one male goat as a sin offering. The people must give two young sheep. They must be one year old. They are a gift to God.
