Deuteronomy 26:2-10

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. 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.” The priest will take your basket and set it down in front of the altar of the LORD your God. Then you shall announce before the LORD your God: “My father was a wandering Aramean. He went down to Egypt with only a few people, but they became a great, powerful, and large nation there. But the Egyptians were cruel to us, making us suffer and work very hard. So we prayed to the LORD, the God of our ancestors, and he heard us. When he saw our trouble, hard work, and suffering, the LORD brought us out of Egypt with his great power and strength, using great terrors, signs, and miracles. Then he brought us to this place and gave us this fertile land. Now I bring part of the first harvest from this land that you, LORD, have given me.” Place the basket before the LORD your God and bow down before him.
