Deuteronomy 14:21-23

Young's Literal Translation

²¹ `Ye do not eat of any carcase; to the sojourner who [is] within thy gates thou dost give it, and he hath eaten it; or sell [it] to a stranger; for a holy people thou [art] to Jehovah thy God; thou dost not boil a kid in its mother's milk.

²² `Thou dost certainly tithe all the increase of thy seed which the field is bringing forth year by year;

²³ and thou hast eaten before Jehovah thy God, in the place where He doth choose to cause His name to tabernacle, the tithe of thy corn, of thy new wine, and of thine oil, and the firstlings of thy herd, and of thy flock, so that thou dost learn to fear Jehovah thy God all the days.
