Exodus 23:9-12

ASV(i) 9 And a sojourner shalt thou not oppress: for ye know the heart of a sojourner, seeing ye were sojourners in the land of Egypt.
10 And six years thou shalt sow thy land, and shalt gather in the increase thereof: 11 but the seventh year thou shalt let it rest and lie fallow; that the poor of thy people may eat: and what they leave the beast 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 have rest, and the son of thy handmaid, and the sojourner, may be refreshed.
