“And thou shalt rejoice in every good thing which the LORD thy God hath given unto thee, and unto thine house, thou, and the Levite, and the stranger that is among you” (Deuteronomy 26:11).
The offering in the context of today’s Scripture (verses 1-11) is spoken as though the nation Israel has already defeated the inhabitants of the Promised Land. It assumes that the Israelites will go in, conquer all their enemies, and enjoy the fruits of the land God has given to the fathers Abraham, Isaac, and Jacob. God through Moses presents Israel residing in the Promised Land as a fact, even though they will not actually enter it and fight those peoples until Joshua assumes leadership (after Moses dies). As before, God believes that He will give Israel the victory. He expects Israel to believe Him, and to worship Him by offering to Him that fruit when they do arrive in that land of Canaan.
Some 40 years prior, remember again, the Jews had complained that they were unable to enter the Promised Land and enjoy its plenteous food supply. The giants living in the land were just too powerful for them to overcome in war. (Of course, Israel overlooked the fact that God had just vanquished the mighty Egyptian armies, thousands of trained soldiers, using just the Red Sea!) With this new generation of Jews in today’s Scripture, they are to go into the land, dispossess it, and rejoice in God’s goodness. They did not deserve that harvest of enormous fruits, but God had simply given them because of His grace.
“And [JEHOVAH God] hath brought us into this place, and hath given us this land, even a land that floweth with milk and honey. And now, behold, I have brought the firstfruits of the land, which thou, O LORD, hast given me. And thou shalt set it before the LORD thy God, and worship before the LORD thy God: And thou shalt rejoice in every good thing which the LORD thy God hath given unto thee, and unto thine house, thou, and the Levite, and the stranger that is among you.” source
