Luke 18:1-6

1 And he spoke a parable to them [to this end], that men ought always [to] pray, and not to faint;

2 Saying, There was in a city a judge, who feared not God, neither regarded man.

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

4 And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man;

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

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