And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary.

Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.

Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.

And having in a readiness to revenge all disobedience, when your obedience is fulfilled.

And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?

For true and righteous are his judgments: for he hath judged the great whore, which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand.
