Exodus 23:13

10 Six years thou shalt sow thy ground, and shalt gather the corn thereof.

11 But the seventh year thou shalt let it alone, and suffer it to rest, that the poor of thy people may eat, and whatsoever shall be left, let the beasts of the field eat it: so shalt thou do with thy vineyard and thy oliveyard.

12 Six days thou shalt work: the seventh day thou shalt cease, that thy ox and thy ass may rest: and the son of thy handmaid and the stranger may be refreshed.

13 Keep all things that I have said to you. And by the name of strange gods you shall not swear, neither shall it be heard out of your mouth.

14 Three times every year you shall celebrate feasts to me.

15 Thou shalt keep the feast of unleavened bread. Seven days shalt thou eat unleavened bread, as I commanded thee, in the time of the month of new corn, when thou didst come forth out of Egypt: thou shalt not appear empty before me.

16 And the feast of the harvest of the firstfruits of thy work, whatsoever thou hast sown in the field. The feast also in the end of the year, when thou hast gathered in all thy corn out of the field.
