Leviticus 23: 18 - 21
18 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. 19 Then
sacrifice one male goat for a sin offering and two lambs, each a
year old, for a fellowship offering. 20 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. 21 On that same day you are to proclaim a sacred
assembly and do no regular work. This is to be a lasting ordinance
for the generations to come, wherever you live.
