Luke XVIII, 1. And he spake a parable unto them to this end, that men ought always to pray, and not to faint;

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

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

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

8. I tell you that he will avenge them speedily. Nevertheless, when the Son of man cometh, shall he find faith on the earth?

Gen. XXXII, 24. And Jacob was left alone; and there wrestled a man with him until the breaking of the day.

25. And when he saw that he prevailed not against him, he touched the hollow of his thigh: and the hollow of Jacob's thigh was out of joint, as he wrestled with him.
