22 Be sure to set aside a tenth of all that your fields produce each year. 23 Eat the tithe of your grain, new wine and oil, and the firstborn of your herds and flocks in the presence of the LORD your God at the place he will choose as a dwelling for his Name, so that you may learn to revere the LORD your God always. (Deuteronomy 14:22-3)

12 When you have finished setting aside a tenth of all your produce in the third year, the year of the tithe, you shall give it to the Levite, the alien, the fatherless and the widow, so that they may eat in your towns and be satisfied. (Deuteronomy 26:12)
