Exodus 22:20-25

20He that sacrificeth unto any god, save unto the LORD only, shall be utterly destroyed.

21And a stranger shalt thou not wrong, neither shalt thou oppress him: for ye were strangers in the land of Egypt.

22Ye shall not afflict any widow, or fatherless child.

23If thou afflict them in any wise, and they cry at all unto me, I will surely hear their cry;

24and my wrath shall wax hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.

25If thou lend money to any of my people with thee that is poor, thou shalt not be to him as a creditor; neither shall ye lay upon him usury.
