Deuteronomy 26:3-11

26:3 You must go to the priest in office at that time and say to him, “I declare today to the Lord your God that I have come into the land that the Lord promised to our ancestors to give us.” 26:4 The priest will then take the basket from you and set it before the altar of the Lord your God. 26:5 Then you must affirm before the Lord your God, “A wandering Aramean was my ancestor, and he went down to Egypt and lived there as a foreigner with a household few in number, but there he became a great, powerful, and numerous people. 26:6 But the Egyptians mistreated and oppressed us, forcing us to do burdensome labor. 26:7 So we cried out to the Lord, the God of our ancestors, and he heard us and saw our humiliation, toil, and oppression. 26:8 Therefore the Lord brought us out of Egypt with tremendous strength and power, as well as with great awe-inspiring signs and wonders. 26:9 Then he brought us to this place and gave us this land, a land flowing with milk and honey. 26:10 So now, look! I have brought the first of the ground’s produce that you, Lord, have given me.” Then you must set it down before the Lord your God and worship before him. 26:11 You will celebrate all the good things that the Lord your God has given you and your family, along with the Levites and the resident foreigners among you.
