Exodus 22:21–242 votes
Thou shalt neither vex a stranger, nor oppress him: for ye were strangers in the land of Egypt. Ye shall not afflict any widow, or fatherless child. If thou afflict them in any wise, and they cry at all unto me, I will surely hear their cry; And my wrath shall wax hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.

And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary. And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man; Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.

And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the stranger from his right, and fear not me, saith the Lord of hosts.
