10 Say to the children of Israel, When you have come to the land which I will give you, and have got in the grain from its fields, take some of the first-fruits of the grain to the priest; 11 And let the grain be waved before the Lord, so that you may be pleasing to him; on the day after the Sabbath let it be waved by the priest. 12 And on the day of the waving of the grain, you are to give a male lamb of the first year, without any mark, for a burned offering to the Lord. 13 And let the meal offering with it be two tenth parts of an ephah of the best meal mixed with oil, an offering made by fire to the Lord for a sweet smell; and the drink offering with it is to be of wine, the fourth part of a hin. 14 And you may take no bread or dry grain or new grain for food till the very day on which you have given the offering for your God: this is a rule for ever through all your generations wherever you are living.

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.

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.
