“For Bethsaida appears to have been infected with much infidelity, wherefore the Lord reproaches it, (Matt. 11:21) Woe to thee, Bethsaida, for if the mighty works which were done in you had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. He then takes out of the town the blind man, who had been brought to Him, for the faith of those who brought him was not true faith. It goes on; And when he had spit in his eyes, and put his hands upon him, he asked him if he saw ought.”

“And taking the blind man by the hand, He led him out of the town , i.e ., outside of Bethsaida, as is plain from ver. 22. He led him forth for the same reason that when He was about to 412 S. MARK, C. VIII. heal the deaf and dumb man He took him aside from the multitude. This was, ist. For the sake of prayer, that, being alone. He might collect His thoughts, and unite Himself wholly to God, and pray the more intently and collectedly, and. To fly from the applause of men, and teach us to do the same. 3rd. Because the citizens of Bethsaida were unworthy of the miracle of Christ ; for although they had seen Him work so many miracles, they would not believe in Him. And spitting upon his eyes . Fasting spittle does good to the purblind, but does not illuminate those who have actually lost their sight. The saliva, therefore, of Christ was not a natural but a supernatural remedy for blindness, being the instrument by which Christ’s Godhead wrought S. Hilarion imitated this miracle by which Christ gave sight to a blind man, as S. Jerome relates in his Life . “A blind woman was brought to B. Hilarion, who said that she had expended all her substance upon physicians. Hilarion said to her, If thou hadst given to the poor what thou hast thrown away upon physicians, Christ the true Physician would have healed thee.” Laid His hands , i.e., when He had placed His hands upon the eyes of the blind man, and again removed them. For that is improbable which the Scholiast in S. Chrysostom says, that this blind man saw people (ver. 24) when Christ’s hands were over his eyes. For this would have been a new and uncalled-for miracle”

“And he took the blind man by the hand,.... Not for the sake of touching him, in order to heal him, as they desired, but to be his guide: and led him out of the town; to shun all appearance of vain glory and popular applause, being willing to do the miracle in a private manner; and because of the obstinacy and unbelief of the inhabitants of this place, who were not worthy to be witnesses of such a cure; see Mat 11:21; and when he had spit on his eyes; not as a cause of healing him; for whatever use spittle may be of to such that have weak eyes, it can have no causal influence upon, or be of any service, in a natural way, to a blind man to restore his sight unto him: and put his hands upon him; as he sometimes did, when he healed persons of any disorder: he asked him, if he saw ought; any object whatever, whether he could perceive he had any sight at all. Christ's taking the blind man by the hand, and leading him out or the town, and spitting on his eyes, and putting his hands upon him, and then asking him if he saw ought, are emblematical of what he does in spiritual conversion, when he turns men from darkness to light: he takes them by the hand, which expresses his condescension, grace, and mercy, and becomes their guide and leader; and a better, and safer guide they cannot have; he brings them by a way they know not, and leads them in paths they had not known before; makes darkness light before them, and crooked things straight, and does not forsake them: he takes them apart, and separates them from the rest of the world; he calls them out from thence to go with him, teaching them, that, when enlightened by him, they should have no fellowship with the unfruitful works of darkness, and the workers of them; for what communion has light with darkness? his putting spittle upon his eyes, may signify the means of grace, the eye salve of the word, which, when attended with a divine power, enlightens the eyes; and which power may be represented here by Christ's putting his hands upon the man; for the Gospel, without the power of Christ, Is insufficient to produce such an effect; but when it is accompanied with that, it always succeeds.”

“And he took the blind man by the hand - Giving him a proof of his readiness to help him, and thus preparing him for the cure which he was about to work. Led him out of the town - Thus showing the inhabitants that he considered them unworthy of having another miracle wrought among them. He had already deeply deplored their ingratitude and obstinacy: see on Mat 11:21 (note). When a people do not make a proper improvement of the light and grace which they receive from God, their candlestick is removed - even the visible Church becomes there extinct; and the candle is put out - no more means of spiritual illumination are afforded to the unfaithful inhabitants: Rev 2:5. When he had spit on his eyes - There is a similar transaction to this mentioned by John, Joh 9:6. It is likely this was done merely to separate the eyelids; as, in certain cases of blindness, they are found always gummed together. It required a miracle to restore the sight, and this was done in consequence of Christ having laid his hands upon the blind man: it required no miracle to separate the eyelids, and, therefore, natural means only were employed - this was done by rubbing them with spittle; but whether by Christ, or by the blind man, is not absolutely certain. See on Mar 7:33 (note). It has always been evident that false miracles have been wrought without reason or necessity, and without any obvious advantage; and they have thereby been detected: on the contrary, true miracles have always vindicated themselves by their obvious utility and importance; nothing ever being effected by them that could be performed by natural means. If he saw aught - Ει, if, is wanting in the Syriac, all the Persic and Arabic, and in the Ethiopic; and τι βλεπεις, Dost thou see any thing? is the reading of CD, Coptic, Ethiopic, all the Arabic and Persic.”

“It may be asked, why our Lord led the man from the multitude before he cured him? — It may be answered, that he did it not to seem to perform his prodigies through vain glory; and thence to teach us to shun the empty praises of men: 2dly, to facilitate recollection, and to give himself to prayer, before he cured the blind man; and lastly, he went out of the city because the inhabitants of Bethsaida had already rendered themselves unworthy of the miracles of Christ. For among them our Saviour had wrought many miracles, yet they would not believe. (St. Matthew xi. 21.) (Tirinus) (Theophylactus) — Dionysius says, that Jesus led him from the multitude to shew that if a sinner, figured by the blind man, wishes to be converted from his evil ways, he must first leave all immediate occasions and inducements to sin. (Dionysius)”

“And He brings him out of the town, that is, out of the neighbourhood of the wicked; and He puts spittle into his eyes, that he may see the will of God, by the breath of the Holy Ghost; and putting His hands upon him, He asked him if he could see, because by the works of the Lord His majesty is seen.”
