The Triennial (Poor) Tithe

Deuteronomy 14:28-29

The third year thou shalt separate another tithe of all things that grow to thee at that time, and shalt lay it up within thy gates.

And the Levite that hath no other part nor possession with thee, and the stranger and the fatherless and the widow, that are within thy gates, shall come and shall eat and be filled: that the Lord thy God may bless thee in all the works of thy hands that thou shalt do.
