And behold, a woman which was a Canaanite came out of the same coasts, and cried unto him, saying, "Have mercy on me Lord, thou son of David, my daughter is piteously vexed with a devil."

"Master have mercy on my son, for he is lunatic, and is sore vexed. And ofttimes, he falleth into the fire, and oft into the water.

And behold, two blind men sitting by the wayside, when they heard that Jesus passed by, cried, saying, "Master, the son of David have mercy on us."

And the people rebuked them, because they should hold their peace: But they cried the more, saying, "Have mercy on us, Master, which art the son of David."
