Luke 18:1

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.

Do read the surrounding verses too, because the context often says more than a single verse.
