Deuteronomy 26:12-13

12“1When you have finished 2paying all the tithe of your increase in the third year, the year of tithing, then you shall give it to the Levite, to the stranger, to the 3orphan and to the widow, that they may eat in your 4towns and be satisfied.

13You shall say before the Lord your God, ‘I have removed the sacred portion from my house, and also have given it to the Levite and the alien, the 5orphan and the widow, according to all Your commandments which You have commanded me; 6I have not transgressed or forgotten any of Your commandments.
