4 "These are the appointed feasts of the Lord, the holy convocations, which you shall proclaim at the time appointed for them 5 In the first month, on the fourteenth day of the month at twilight,[1] is the Lord's Passover. 6 And on the fifteenth day of the same month is the Feast of Unleavened Bread to the Lord; for seven days you shall eat unleavened bread. 7 On the first day you shall have a holy convocation; you shall not do any ordinary work. 8 But you shall present a food offering to the Lord for seven days. On the seventh day is a holy convocation; you shall not do any ordinary work." 9 And the Lord spoke to Moses, saying, 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.

Matthew Henry's Commentary on Leviticus 23:4-11

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.
