Luke 18:5 KJV

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;

And the Lord said, Hear what the unjust judge saith.

And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
