Leviticus 23:18-20
23:18 Along with the loaves of bread, you must also present seven flawless yearling lambs, one young bull, and two rams. They are to be a burnt offering to the Lord along with their grain offering and drink offerings, a gift of a soothing aroma to the Lord.
23:19 You must also offer one male goat for a sin offering and two yearling lambs for a peace offering sacrifice,
23:20 and the priest is to wave them – the two lambs – along with the bread of the first fruits, as a wave offering before the Lord; they will be holy to the Lord for the priest.
