10 Speak unto the children of Israel and say unto them, When ye come into the land that I give unto you, and ye reap the harvest thereof, then ye shall bring a sheaf of the first-fruits of your harvest unto the priest. 11 And he shall wave the sheaf before Jehovah, to be accepted for you; on the next day after the sabbath the priest shall wave it. 12 And ye shall offer that day when ye wave the sheaf, a he-lamb without blemish, a yearling, for a burnt-offering to Jehovah; 13 and the oblation thereof: two tenths of fine flour mingled with oil, an offering by fire to Jehovah for a sweet odour; and the drink-offering thereof, of wine, a fourth part of a hin. 14 And ye shall not eat bread, or roast corn, or green ears, until the same day that ye have brought the offering of your God: [it is] an everlasting statute throughout your generations in all your dwellings.

15 And ye shall count from the morning after the sabbath, from the day that ye brought the sheaf of the wave-offering, seven weeks; they shall be complete; 16 even unto the morning after the seventh sabbath shall ye count fifty days; and ye shall present a new oblation to Jehovah.

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.
