The parable "Persistent Widow"
18:2 Saying, There was in a city a judge, which feared not God, neither regarded man:
18:3 And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary.
18:4 And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man;
18:5 Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.
18:6 And the Lord said, Hear what the unjust judge saith.
18:7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
18:8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?
