Exodus 23:11

8 And thou shalt take no gift: for the gift blindeth the wise, and perverteth the words of the righteous.

9 Also thou shalt not oppress a stranger: for ye know the heart of a stranger, seeing ye were strangers in the land of Egypt.

10 And six years thou shalt sow thy land, and shalt gather in the fruits thereof:

11 But the seventh year thou shalt let it rest and lie still; that the poor of thy people may eat: and what they leave the beasts of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thy oliveyard.

12 Six days thou shalt do thy work, and 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.

13 And in all things that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.

14 Three times thou shalt keep a feast unto me in the year.
