'Mercy' in the Bible

And he suffered him not, but says to him, Go to thine home to thine own people, and tell them how great things the Lord has done for thee, and has had mercy on thee.

And having heard that it was Jesus the Nazaraean, he began to cry out and to say, O Son of David, Jesus, have mercy on me.

And many rebuked him, that he might be silent; but he cried so much the more, Son of David, have mercy on me.
