“‘Speak to the Israelites and say to them: “When you enter the land I am going to give you and you reap its harvest, bring to the priest a sheaf of the first grain you harvest. He is to wave the sheaf before the Lord so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath.”
Waving is an act of drawing attention, of signaling recognition. Whose attention is being drawn by the waving of this sheaf?
God, of course, needs no reminder, but we benefit from the act of presenting the fruit of our labor to His purposes. The act of dedication draws our attention to truths like, it was God who created and strengthened our hands to work, gifted us the land we tilled, and all we do is to His glory not ours.
We draw our attention to the benefits of His blessings. “This is Your harvest from which I am benefiting.”
