John 9:6,7

When he had thus spoken, he spat on the ground, &c. He did the things here mentioned, that he might exercise the faith and obedience of the patient, and show that he could command efficacy from whatever means he should please to use; could work without means, or even by such as seemed evidently calculated to produce an effect contrary to that intended. The clay, here put on the eyes of the blind man, might almost have blinded a person that had sight. But what could it do toward curing the blind? It reminds us that God is no farther from the event designed, whether he uses any means to accomplish it or not; and that all the creatures are only that which his almighty operation makes them. To try still further the faith and submission of the blind man, Jesus said unto him, Go, wash in the pool of Siloam Perhaps, by giving this command, our Lord intended to make the miracle more taken notice of. For a crowd of people would naturally gather round the man, to observe the event of so strange a prescription. And it is exceeding probable that the guide who must have led him, in traversing a great part of the city, would mention the errand he was going upon, and so call those who saw him to a greater attention. Which is by interpretation, Sent And so was a type of the Messiah, who was sent of God. This remark, Grotius and Dr. S. Clarke think was designed to intimate, that Christ's command to the blind man was symbolical, teaching him that he owed his cure to the Messiah, one of whose names was Shiloh, the sent of God. The waters here mentioned came from a spring that was in the rocks of mount Zion, and were gathered into two great basins, the lower called the Pool of Fleeces, and the upper, Shiloah, because the waters that filled it were sent to them by the goodness of God, from the bowels of the earth; for in Judea springs of water, being very rare, were esteemed peculiar blessings. Hence the waters of Shiloah were made by the prophet a type of David's descendants, and among the rest, of the Messiah, Isaiah 8:5: whose benefits are fitly represented by the image of water, for his blood purifies the soul from the foulest stains of sin, just as water cleanses the body from its defilements. Moreover, his doctrine imparts wisdom, and affords refreshment to the spirit, like that which cool draughts of water impart to one who is ready to faint away with thirst and heat. He went, therefore, and washed, and came seeing He believed, and obeyed, and obtained the blessing he desired. Had he been wise in his own eyes, and reasoned like Naaman, on the impropriety of the means, he would justly have been left in darkness. Lord, may our proud hearts be subdued to the methods of thy recovering grace! May we leave thee to choose how thou wilt bestow favours which it is our highest interest to receive on any terms. This amazing miracle was, doubtless, wrought in the presence of great numbers of people, partly accompanying the man as he passed along the streets, and partly of such as he found at the pool, which was a place much frequented. All these, seeing him led thither blind, with his eyes bedaubed with clay, must have gathered about him, eager to know the cause of so strange an appearance. And “having examined and found that he was stone blind, they could not but be prodigiously struck with his relation, when, after washing in the pool, they saw the new faculty instantly imparted to him; especially if his relation was confirmed by the person who led him, as in all probability it would be. For it is reasonable to suppose, that his conductor was one of them who stood by when Jesus anointed his eyes, and ordered him to wash them in Siloam. Accordingly, when he went away, and washed, and came seeing, that is, walked by the assistance of his own eyes, without being led, the miracle was earnestly and accurately inquired into by all his acquaintance, and was so universally known, that it became the general topic of conversation at Jerusalem, as the evangelist informs us, John 9:8; nay, it was accurately examined by the literati there. For the man was brought before them; they looked at his eyes; they inquired what had been done to them; they sent for his parents, to know from them if he had been really born blind; and they excommunicated the man, because he would not join them in saying that Jesus, who had cured him, was an impostor.”
