'Have Mercy' in the Bible

And he cried and said, 'Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue, for I am tormented in this flame.'

and put forth their voices, and said, "Jesus, Master, have mercy on us."

And they which went before rebuked him, that he should hold his peace. But he much the more so cried, "Thou son of David, have mercy on me."
