Deuteronomy 14:22 in the King James Version
Thou shalt truly tithe all the increase of thy seed, that the field bringeth forth year by year.
Context
21 You shall not eat of anything that dies of itself. You may give it to the foreigner living among you who is within your gates, that he may eat it; or you may sell it to a foreigner; for you are a holy people to the LORD your God. You shall not boil a young goat in its mother’s milk.
22 You shall surely tithe all the increase of your seed, that which comes out of the field year by year.
23 You shall eat before the LORD your God, in the place which he chooses to cause his name to dwell, the tithe of your grain, of your new wine, and of your oil, and the firstborn of your herd and of your flock; that you may learn to fear the LORD your God always.
