Exodus 23:10-19

And six years thou shalt sow thy land, and shalt gather in the increase thereof: but the seventh year thou shalt let it rest and lie fallow; that the poor of thy people may eat: and what they leave the beast of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thy oliveyard. Six days thou shalt do thy work, and on the seventh day thou shalt rest; that thine ox and thine ass may have rest, and the son of thy handmaid, and the sojourner, may be refreshed. And in all things that I have said unto you take ye heed: and make no mention of the name of other gods, neither let it be heard out of thy mouth. Three times thou shalt keep a feast unto me in the year. The feast of unleavened bread shalt thou keep: seven days thou shalt eat unleavened bread, as I commanded thee, at the time appointed in the month Abib (for in it thou camest out from Egypt); and none shall appear before me empty: and the feast of harvest, the first-fruits of thy labors, which thou sowest in the field: and the feast of ingathering, at the end of the year, when thou gatherest in thy labors out of the field. Three times in the year all thy males shall appear before the Lord Jehovah. Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the fat of my feast remain all night until the morning. The first of the first-fruits of thy ground thou shalt bring into the house of Jehovah thy God. Thou shalt not boil a kid in its mother’s milk.
