'Mercy' in the Bible

But He would not let him; instead, He told him, “Go back home to your own people, and report to them how much the Lord has done for you and how He has had mercy on you.”

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

And many charged him that he should hold his peace: but he cried the more a great deal, Thou Son of David, have mercy on me.
