Deuteronomy 26:12-15

Bring a tenth of all your harvest the third year (the year to give a tenth of your harvest). Give it to the Levites, foreigners, orphans, and widows so that they may eat in your towns and be full. Then say to the LORD your God, “I have taken out of my house the part of my harvest that belongs to God, and I have given it to the Levites, foreigners, orphans, and widows. I have done everything you commanded me; I have not broken your commands, and I have not forgotten any of them. I have not eaten any of the holy part while I was in sorrow. I have not removed any of it while I was unclean, and I have not offered it for dead people. I have obeyed you, the LORD my God, and have done everything you commanded me. So look down from heaven, your holy home. Bless your people Israel and bless the land you have given us, which you promised to our ancestors—a fertile land.”
