Deuteronomy 14:27-29

New Revised Standard Version, Anglicised Catholic Edition

²⁷ As for the Levites resident in your towns, do not neglect them, because they have no allotment or inheritance with you.

²⁸ Every third year you shall bring out the full tithe of your produce for that year, and store it within your towns; ²⁹ the Levites, because they have no allotment or inheritance with you, as well as the resident aliens, the orphans, and the widows in your towns, may come and eat their fill so that the Lord your God may bless you in all the work that you undertake.
