Deuteronomy 14
22 Ref Put on one side a tenth of all the increase of your seed, produced year by year.
23 Ref And make a feast before the Lord your God, in the place which is to be marked out, where his name will be for ever, of the tenth part of your grain and your wine and your oil, and the first births of your herds and your flocks; so that you may have the fear of the Lord your God in your hearts at all times.
