Verse 38. - Jesus, thou Son of David. This form of address distinctly shows that the idea that the Rabbi of Nazareth, the great Wonder-worker, the wise kind Teacher, was in some way or other the long looked-for Deliverer, was now taking possession of the people's mind. "Son of David" was distinctly a Messianic salutation.

18:35-43 This poor blind man sat by the wayside, begging. He was not only blind, but poor, the fitter emblem of the world of mankind which Christ came to heal and save. The prayer of faith, guided by Christ's encouraging promises, and grounded on them, shall not be in vain. The grace of Christ ought to be thankfully acknowledged, to the glory of God. It is for the glory of God if we follow Jesus, as those will do whose eyes are opened. We must praise God for his mercies to others, as well as for mercies to ourselves. Would we rightly understand these things, we must come to Christ, like the blind man, earnestly beseeching him to open our eyes, and to show us clearly the excellence of his precepts, and the value of his salvation.And he cried, saying, Jesus thou son of David,.... Believing him, at once, to be the Messiah; whence he calls him the son of David, which was a character and title of the Messiah, well known to the Jews; See Gill on Matthew 1:1 and therefore immediately called out unto him, being willing to take that opportunity as he passed, and whilst he was within hearing, to make his suit to him for his sight:

saying, have mercy on me: a poor, blind, and miserable creature, and restore me to my sight, which will be an act of singular mercy, and goodness, and will always be gratefully owned as such.
