'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 in anguish in this flame.

and they lifted up their voices, saying, Jesus, Master, have mercy on us.

And he cried, saying, Jesus, thou son of David, have mercy on me.

And they that went before rebuked him, that he should hold his peace: but he cried out the more a great deal, Thou son of David, have mercy on me.
