15 And from the day after the sabbath, from the day on which you bring the sheaf of the elevation offering, you shall count off seven weeks; they shall be complete. 16 You shall count until the day after the seventh sabbath, fifty days; then you shall present an offering of new grain to the Lord. 17 You shall bring from your settlements two loaves of bread as an elevation offering, each made of two-tenths of an ephah; they shall be of choice flour, baked with leaven, as first fruits to the Lord.

Matthew Henry's Commentary on Leviticus 23:15-17

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.
