Deuteronomy 26:10-13

and now, behold, I have brought the firstfruits of the land which you, O LORD, have given me.’ “Then you shall set it before the LORD your God, and worship before the LORD your God. So you shall rejoice in every good thing which the LORD your God has given to you and your house, you and the Levite and the stranger who is among you. “When you have finished laying aside all the tithe of your increase in the third year—the year of tithing—and have given it to the Levite, the stranger, the fatherless, and the widow, so that they may eat within your gates and be filled, then you shall say before the LORD your God: ‘I have removed the holy tithe from my house, and also have given them to the Levite, the stranger, the fatherless, and the widow, according to all Your commandments which You have commanded me; I have not transgressed Your commandments, nor have I forgotten them.
