10 "Speak to the people of Israel and say to them, When you come into the land that I give you and reap its harvest, you shall bring the sheaf of the firstfruits of your harvest to the priest, 11 and he shall wave the sheaf before the Lord, so that you may be accepted. On the day after the Sabbath the priest shall wave it. 12 And on the day when you wave the sheaf, you shall offer a male lamb a year old without blemish as a burnt offering to the Lord. 13 And the grain offering with it shall be two tenths of an ephah[1] of fine flour mixed with oil, a food offering to the Lord with a pleasing aroma, and the drink offering with it shall be of wine, a fourth of a hin.[2] 14 And you shall eat neither bread nor grain parched or fresh until this same day, until you have brought the offering of your God: it is a statute forever throughout your generations in all your dwellings

15 "You shall count seven full weeks from the day after the Sabbath, from the day that you brought the sheaf of the wave offering. 16 You shall count fifty days to the day after the seventh Sabbath. Then you shall present a grain offering of new grain to the Lord.

Commentary on Leviticus 23:4-14

(Read Leviticus 23:4-14)

The feast of the Passover was to continue seven days; not idle days, spent in sport, as many that are called Christians spend their holy-days. Offerings were made to the Lord at his altar; and the people were taught to employ their time in prayer, and praise, and godly meditation. The sheaf of first-fruits was typical of the Lord Jesus, who is risen from the dead as the First-fruits of them that slept. Our Lord Jesus rose from the dead on the very day that the first-fruits were offered. We are taught by this law to honour the Lord with our substance, and with the first-fruits of all our increase, Proverbs 3:9. They were not to eat of their new corn, till God's part was offered to him out of it; and we must always begin with God: begin every day with him, begin every meal with him, begin every affair and business with him; seek first the kingdom of God.

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.
