'Be Merciful' in the Bible

And having cried out, he said, Father Abraham, be merciful to me, and send Lazarus, so that he may dip the tip of his finger in water, and cool my tongue, because I am in agony in this flame.

And they raised a voice, saying, Jesus, Master, be merciful to us.

And he cried out, saying, Jesus, thou son of David, be merciful to me.

And those who went ahead rebuked him, so that he would be quiet, but he cried out much more, Thou son of David, be merciful to me.
