Leviticus 23:15-21

‘ “From the day after the Sabbath, the day you brought the sheaf of the wave offering, count seven full weeks. Count fifty days up to the day after the seventh Sabbath, and then present an offering of new grain to the LORD. From wherever you live, bring two loaves made of one-fifth of an ephah of the finest flour, baked with yeast, as a wave offering of firstfruits to the LORD. Present with this bread seven male lambs, each a year old and without defect, one young bull and two rams. They will be a burnt offering to the LORD, together with their grain offerings and drink offerings – a food offering, an aroma pleasing to the LORD. Then sacrifice one male goat for a sin offering and two lambs, each a year old, for a fellowship offering. The priest is to wave the two lambs before the LORD as a wave offering, together with the bread of the firstfruits. They are a sacred offering to the LORD for the priest. On that same day you are to proclaim a sacred assembly and not do any ordinary work. This is to be a lasting ordinance for the generations to come, wherever you live.
