'Have Mercy' in the Bible

Happy are those who have mercy: for they will be given mercy.

And when Jesus went on from there, two blind men came after him, crying out, Have mercy on us, you Son of David.

Lord have mercy on my son: for he is off his head, and is in great pain; and frequently he goes falling into the fire, and frequently into the water.

Was it not right for you to have mercy on the other servant, even as I had mercy on you?

And two blind men seated by the wayside, when they had the news that Jesus was going by, gave a loud cry, saying, Lord, Son of David, have mercy on us.

And the people gave them orders to be quiet; but they went on crying even louder, Lord, Son of David, have mercy on us.
