15 And let seven full weeks be numbered from the day after the Sabbath, the day when you give the grain for the wave offering; 16 Let fifty days be numbered, to the day after the seventh Sabbath; then you are to give a new meal offering to the Lord. 17 Take from your houses two cakes of bread, made of a fifth part of an ephah of the best meal, cooked with leaven, to be waved for first-fruits to the Lord. 18 And with the bread, take seven lambs of the first year, without any marks, and one ox and two male sheep, to be a burned offering to the Lord, with their meal offering and their drink offerings, an offering of a sweet smell made by fire to the Lord. 19 And you are to give one male goat for a sin-offering and two male lambs of the first year for peace-offerings. 20 And these will be waved by the priest, with the bread of the first-fruits, for a wave offering to the Lord, with the two lambs: they will be holy to the Lord for the priest. 21 And on the same day, let it be given out that there will be a holy meeting for you: you may do no field-work on that day: it is a rule for ever through all your generations wherever you are living. 22 And when you get in the grain from your land, do not let all the grain at the edges of the field be cut, and do not take up the grain which has been dropped in the field; let that be for the poor, and for the man from another country: I am the Lord your God.

Matthew Henry's Commentary on Leviticus 23:15-22

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.
