Exodus 22:21-24

“You must not mistreat or oppress foreigners in any way. Remember, you yourselves were once foreigners in the land of Egypt. “You must not exploit a widow or an orphan. If you exploit them in any way and they cry out to me, then I will certainly hear their cry. My anger will blaze against you, and I will kill you with the sword. Then your wives will be widows and your children fatherless.
