'Have Mercy' in the Bible

And often times casteth him into the fire, and also into the water, to destroy him. But if thou canst do anything, have mercy on us, and help us."

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.
