Luke 18:1-7

Now he also told them a parable, that we should continually pray and not cease, saying: "There was a certain judge in a certain city, who did not fear God and did not respect man. But there was a certain widow in that city, and she went to him, saying, 'Vindicate me from my adversary.' And he refused to do so for a long time. But afterwards, he said within himself: 'Even though I do not fear God, nor respect man, yet because this widow is pestering me, I will vindicate her, lest by returning, she may, in the end, wear me out.' " Then the Lord said: "Listen to what the unjust judge said. So then, will not God grant the vindication of his elect, who cry out to him day and night? Or will he continue to endure them?
