'Mercy' in the Bible

And he suffered him not, but saith unto him, Go to thy house unto thy friends, and tell them how great things the Lord hath done for thee, and how he had mercy on thee.

And when he heard that it was Jesus the Nazarene, he began to cry out, and say, Jesus, thou son of David, have mercy on me.

And many 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.
