Matthew 15:31

What the Latin translator calls 'debiles' (maimed), is in the Greek χυλλοὺς which is not a general term for a maimed person, but a peculiar species, as he that is lame in one foot is called 'claudus,' so he that is crippled in one hand is called χυλλός. He said nothing concerning the maimed, because there was no one word which was the opposite of thisa.

"And Jesus departed from thence, and came nigh unto the sea of Galilee; and went up into the mountain, and sat down there. And great multitudes came unto Him, having with them those that were lame, blind, maimed, dumb; and cast them at His feet; and He healed them, insomuch that the multitudes wondered, when they saw the dumb to speak, the maimed to be whole, the lame to walk, and the blind to see, and they glorified the God of Israel." Now He goes about Himself, now sits awaiting the diseased, and hath the lame brought up unto the mountain. And no longer do they touch so much as His garment, but advance a higher step, being cast at His feet: and they showed their faith doubly, first, by going up into the mountain though lame, then by wanting nothing else but to be cast at His feet only. And great was the marvel and strange, to see them that were carried walking, the blind needing not any to lead them by the hand. Yea, both the multitude of the healed, and the facility of their cure amazed them. Seest thou, how the woman indeed He healed with so much delay, but these immediately? not because these are better than she is, but because she is more faithful than they. Therefore, while in her case He defers and delays, to manifest her constancy; on these He bestows the gift immediately, stopping the mouths of the unbelieving Jews, and cutting away from them every plea. For the greater favors one hath received, so much the more is he liable to punishment, if he be insensible, and the very honor make him no better.

Mystically; Having in the daughter of this Chauanæan prefigured the salvation of the Gentiles, He came into Judæa; because, when the fulness of the Gentiles shall have entered in, then shall all Israel be saved. (Rom. 11:25.) Thus raising his hearers to meditate on heavenly things. He sat down there to show that rest is not to be sought but in heavenly things. And as He sits on the mountain, that is, in the heavenly height, there come unto Him multitudes of the faithful, drawing near to Him with devoted mind, and bringing to Him the dumb, and the blind, & c. and cast them down at Jesus' feet; because they that confess their sins are brought to be healed by Him alone. These He so heals, that the multitudes marvel and magnify the God of Israel; because the faithful when they see those that have been spiritually sick richly endued with all manner of works of virtuousness, sing praise to God.
