22 "You must set aside a tithe of your crops-one-tenth of all the crops you harvest each year. 23 Bring this tithe to the designated place of worship-the place the Lord your God chooses for his name to be honored-and eat it there in his presence. This applies to your tithes of grain, new wine, olive oil, and the firstborn males of your flocks and herds. Doing this will teach you always to fear the Lord your God.

Commentary on Deuteronomy 14:22-29
(Read Deuteronomy 14:22-29)
A second portion from the produce of their land was required. The whole appointment evidently was against the covetousness, distrust, and selfishness of the human heart. It promoted friendliness, liberality, and cheerfulness, and raised a fund for the relief of the poor. They were taught that their worldly portion was most comfortably enjoyed, when shared with their brethren who were in want. If we thus serve God, and do good with what we have, it is promised that the Lord our God will bless us in all the works of our land. The blessing of God is all to our outward prosperity; and without that blessing, the work of our hands will bring nothing to pass. The blessing descends upon the working hand. Expect not that God should bless thee in thy idleness and love of ease. And it descends upon the giving hand. He who thus scatters, certainly increases; and to be free and generous in the support of religion, and any good work, is the surest and safest way of thriving.
