Exodus 23:10-16

10And six years thou shalt sow thy land, and gather in its produce;

11but in the seventh thou shalt let it rest and lie [fallow], that the poor of thy people may eat [of it]; and what they leave, the beasts of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thine olive-tree.

12— Six days thou shalt do thy work, but on the seventh day thou shalt rest; that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger may be refreshed.

13And ye shall be on your guard as to everything that I have said unto you; and shall make no mention of the name of other 1gods — it shall not be heard in thy mouth.

14Thrice in the year thou shalt celebrate a feast to me.

15Thou shalt keep the feast of unleavened bread, (thou shalt eat unleavened bread seven days, as I have commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt; and none shall appear in my presence empty;)

16and the feast of harvest, the first-fruits of thy labours which thou hast sown in the field, and the feast of in-gathering, at the end of the year, when thou gatherest in thy labours out of the field.
