Deuteronomy 26:1-4

“When you enter the land the LORD your God is giving you as a special possession and you have conquered it and settled there, put some of the first produce from each crop you harvest into a basket and bring it to the designated place of worship—the place the LORD your God chooses for his name to be honored. Go to the priest in charge at that time and say to him, ‘With this gift I acknowledge to the LORD your God that I have entered the land he swore to our ancestors he would give us.’ The priest will then take the basket from your hand and set it before the altar of the LORD your God.
