Augustine of Hippo — as excerpted in the Catena Aurea on Matthew 20:29-34

“(Quæst. Ev. i. 28.) Otherwise; The two blind men sitting by the wayside, denote certain of both nations already by faith coming in to that temporal dispensation, according to which Christ is the way, and seeking to be enlightened, that is, to know something concerning the eternity of the Word. This they desired to obtain from the Lord as He passed by, for the merit of that faith by which He is believed to be the Son of God, to have been born man, and to have suffered for us; for in this dispensation, Jesus, as it were, passes by, for all action is of this world. Also it behoved that they should cry out so loud as to overpower the din of the multitude that withstood them; that is, so to fortify their minds by perseverance and prayer, and mortifying continually the usage of fleshly lusts, (which as a crowd ever beset one that is endeavouring to come to the sight of eternal truth,) and by the straitest painfulness to get the better of the multitude of carnal men who hinder spiritual aspirations.”
