Deuteronomy 26:12-15

“Every third year you must offer a special tithe of your crops. In this year of the special tithe you must give your tithes to the Levites, foreigners, orphans, and widows, so that they will have enough to eat in your towns. Then you must declare in the presence of the LORD your God, ‘I have taken the sacred gift from my house and have given it to the Levites, foreigners, orphans, and widows, just as you commanded me. I have not violated or forgotten any of your commands. I have not eaten any of it while in mourning; I have not handled it while I was ceremonially unclean; and I have not offered any of it to the dead. I have obeyed the LORD my God and have done everything you commanded me. Now look down from your holy dwelling place in heaven and bless your people Israel and the land you swore to our ancestors to give us—a land flowing with milk and honey.’
