18 You shall present with the bread seven lambs without blemish a year old, one young bull, and two rams. They shall be a burnt offering to Yahweh, with their meal offering, and their drink offerings, even an offering made by fire, of a sweet aroma to Yahweh. 19 You shall offer one male goat for a sin offering, and two male lambs a year old for a sacrifice of peace offerings. 20 The priest shall wave them with the bread of the first fruits for a wave offering before Yahweh, with the two lambs. They shall be holy to Yahweh for the priest.
Matthew Henry's Commentary on Leviticus 23:18-20
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.
