'Mercy' in the Bible

And he did not permit him, but said to him, "Go to your home to your [people] and tell them all that the Lord has done for you, and [that] he has had mercy on you."

And [when he] heard that it was Jesus the Nazarene, he began to cry out and say, "Jesus, Son of David, have mercy on me!"

And many [people] warned him that he should be quiet. But he was crying out {even more loudly}, "Son of David, have mercy on me!"
