Exodus 23
9 Ref "You shall not oppress an alien, for you know the heart of an alien, seeing you were aliens in the land of Egypt.
10 Ref "For six years you shall sow your land, and shall gather in its increase,
11 Ref but the seventh year you shall let it rest and lie fallow, that the poor of your people may eat; and what they leave the animal of the field shall eat. In like manner you shall deal with your vineyard and with your olive grove.
12 Ref "Six days you shall do your work, and on the seventh day you shall rest, that your ox and your donkey may have rest, and the son of your handmaid, and the alien may be refreshed.
