And he spake a parable unto them to the end that they ought always to
pray, and not to faint; saying, "There was in a city a judge, who
feared not God, and regarded not man: and there was a widow in that
city: and she came oft 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 she wear me out by her
continual coming.'" And the Lord said, "Hear what the unrighteous
judge saith. And shall not God avenge his elect, that cry to him day
and night, and yet he is longsuffering over them? I say unto you, that
he will avenge them speedily. Nevertheless, when the Son of man
cometh, shall he find faith on the earth?"
