Exodus 23:9-11

9“1You shall not oppress a stranger, since you yourselves know the 2feelings of a stranger, for you also were strangers in the land of Egypt.

10“Now 3you shall sow your land for six years and gather in its yield, 11but in the seventh year you shall let it 4rest and lie uncultivated, so that the needy of your people may eat; and whatever they leave the animal of the field may eat. You are to do the same with your vineyard and your olive grove.
