Deuteronomy 26:2-4

2that you shall take some of the first of all the produce of the ground, which you shall bring from your land that the Lord your God is giving you, and put it in a basket and go to the place where the Lord your God chooses to make His name abide.

3And you shall go to the one who is priest in those days, and say to him, ‘I declare today to the Lord your God that I have come to the country which the Lord swore to our fathers to give us.’

4“Then the priest shall take the basket out of your hand and set it down before the altar of the Lord your God.
