Luke 18:1-8 (NKJV)
1 Then He spoke a parable to them, that men always ought to pray and not lose heart,
2 saying: “There was in a certain city a judge who did not fear God nor regard man.
3 Now there was a widow in that city; and she came to him, saying, ‘Get justice for me from my adversary.’
4 And he would not for a while; but afterward he said within himself, ‘Though I do not fear God nor regard man,
5 yet because this widow troubles me I will avenge her, lest by her continual coming she weary me.’ “
6 Then the Lord said, “Hear what the unjust judge said.
7 And shall God not avenge His own elect who cry out day and night to Him, though He bears long with them?
8 I tell you that He will avenge them speedily. Nevertheless, when the Son of Man comes, will He really find faith on the earth?”
