15 " 'From the day after the Sabbath, the day you brought the sheaf of the wave offering, count off seven full weeks. 16 Count off fifty days up to the day after the seventh Sabbath, and then present an offering of new grain to the Lord. 17 From wherever you live, bring two loaves made of two-tenths of an ephah of the finest flour, baked with yeast, as a wave offering of firstfruits to the Lord. 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[1] 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.

Matthew Henry's Commentary on Leviticus 23:15-21

Commentary on Leviticus 23:15-22

(Read Leviticus 23:15-22)

The feast of Weeks was held in remembrance of the giving of the law, fifty days after the departure from Egypt; and looked forward to the outpouring of the Holy Ghost, fifty days after Christ our Passover was sacrificed for us. On that day the apostles presented the first-fruits of the Christian church to God. To the institution of the feast of Pentecost, is added a repetition of that law, by which they were required to leave the gleanings of their fields. Those who are truly sensible of the mercy they received from God, will show mercy to the poor without grudging.
