Deuteronomy 26:12-16

“When you have finished paying all the tithe of your produce in the third year, the year of the tithe, then you shall give it to the Levite, to the stranger, to the orphan, and to the widow, so that they may eat in your towns and be satisfied.

And you shall say before the Lord your God, ‘I have removed the sacred portion from my house, and have also given it to the Levite, the stranger, the orphan, and the widow, in accordance with all Your commandments which You have commanded me; I have not violated or forgotten any of Your commandments.

I have not eaten of it while mourning, nor have I removed any of it while I was unclean, nor offered any of it to the dead. I have listened to the voice of the Lord my God; I have acted in accordance with everything that You have commanded me.

Look down from Your holy dwelling place, from heaven, and bless Your people Israel, and the ground which You have given us, a land flowing with milk and honey just as You swore to our fathers.’

“This day the Lord your God commands you to perform these statutes and ordinances. Therefore you shall be careful to perform them with all your heart and with all your soul.
