Deuteronomy 14:21-23

New Century Version

²¹ Do not eat anything you find that is already dead. You may give it to a foreigner living in your town, and he may eat it, or you may sell it to a foreigner. But you are holy people, who belong to the Lord your God.

Do not cook a baby goat in its mother’s milk.

Giving One-Tenth

²² Be sure to save one-tenth of all your crops each year. ²³ Take it to the place the Lord your God will choose where he is to be worshiped. There, where you will be together with the Lord, eat the tenth of your grain, new wine, and oil, and eat the animals born first to your herds and flocks. Do this so that you will learn to respect the Lord your God always.
