Exodus 22:20-25

20— He that sacrificeth to [any] 1god, save to Jehovah only, shall be devoted to destruction.

21Thou shalt neither vex a stranger, nor oppress him; for ye have been strangers in the land of Egypt.

22Ye shall not afflict any widow or fatherless child.

23If thou afflict him in any way, if he cry at all unto me, I will certainly hear his cry;

24and my anger shall burn, and I will slay you with the sword; and your wives shall be widows, and your children fatherless.

25— If thou lend money to my people, the poor with thee, thou shalt not be to him as a usurer: ye shall charge him no interest.
