Deuteronomy 26:11-13

11You, the Levites, and the resident aliens among you will rejoice in all the good things the Lord your God has given you and your household.

12“When you have finished paying all the tenth of your produce in the third year, the year of the tenth, you are to give it to the Levites, resident aliens, fatherless children, and widows, so that they may eat in your towns and be satisfied.

13Then you will say in the presence of the Lord your God: I have taken the consecrated portion out of my house; I have also given it to the Levites, resident aliens, fatherless children, and widows, according to all the commands you gave me. I have not violated or forgotten your commands.
