Deuteronomy 14:27

25then you shall turn it into money, bind up the money in your hand, and shall go to the place which the LORD your God shall choose.

26You shall trade the money for whatever your soul desires: for cattle, or for sheep, or for wine, or for strong drink, or for whatever your soul asks of you. You shall eat there before the LORD your God, and you shall rejoice, you and your household.

27You shall not forsake the Levite who is within your gates, for he has no portion nor inheritance with you.

28At the end of every three years you shall bring all the tithe of your increase in the same year, and shall store it within your gates.

29The Levite, because he has no portion nor inheritance with you, as well as the foreigner living among you, the fatherless, and the widow who are within your gates shall come, and shall eat and be satisfied; that the LORD your God may bless you in all the work of your hand which you do.
