Exodus 22:20-25

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

21Thou shalt neither vex a stranger, nor 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 that is poor by thee, thou shalt not be to him as an usurer, neither shalt thou lay upon him usury.
