Deuteronomy 26:2-4

New Century Version

² you must take some of the first harvest of crops that grow from the land the Lord your God is giving you. Put the food in a basket and go to the place where the Lord your God will choose to be worshiped. ³ Say to the priest on duty at that time, “Today I declare before the Lord your God that I have come into the land the Lord promised our ancestors that he would give us.” ⁴ The priest will take your basket and set it down in front of the altar of the Lord your God.
