'Have Mercy' in the Bible

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

And he cried, saying, Jesus, Son of David! Have mercy on me.

And they who were in front rebuked him that he should be quiet. But he cried so much the more, Son of David! Have mercy on me.
