| Barnes' Notes on the Bible The sacrifices here meant are named in Numbers 28:19-24.
Gill's Exposition of the Entire BibleBut ye shall offer an offering made by, fire unto the Lord seven days,.... A burnt offering was to be offered unto the Lord on everyone of the seven days, which were two young bullocks, one ram, and seven lambs; besides a meat offering, and a goat for a sin offering, Numbers 28:19, in the seventh day is an holy convocation, ye shall do no servile work therein; as on the first day, that was on account of the Israelites going out of Egypt; and this is said, on account of Pharaoh and his host being drowned on it; See Gill on Exodus 12:16.
Geneva Study BibleBut ye shall offer an offering made by fire unto the LORD seven days: in the {c} seventh day is an holy convocation: ye shall do no servile work therein. (c) The first day of the feast and the seventh were kept holy: in the rest they might work, except any feasts that were together, as were the feast of unleavened bread and the feast of sheaves which were on the fifteenth and sixteenth days.
Matthew Henry's Concise Commentary23:4-14 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, Pr 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. |
