There fell from his eyes as it had been scales. The blindness of Paul, as we have said before did not proceed from fear alone or from amazedness; but by this means was he admonished of his former blindness, that he might quite abandon that boldness and vain confidence wherewith he was puffed up. He boasted that he was taught at the feet of Gamaliel, (Acts 22:3;) and undoubtedly he thought very well of his great wittiness, [1] which was notwithstanding mere blindness. Therefore he is deprived of the sight of his body [2] three days, that he may begin to see with his mind; for those must become fools, whosoever they be, which seem to themselves wise, that they may attain to true wisdom. For seeing that Christ is the Sun of righteousness, in seeing without him we see not; it is he also which openeth the eyes of the mind. Both things were showed to Paul, and to us are they showed in his person; for he hath his eyes covered with scales, that, condemning all his knowledge of ignorance, [3] he may learn that he hath need of new light, which he hath hitherto wanted; and he is taught that he must let [seek] the true light from none other save only from Christ, and that it is given by no other means save only through his goodness. Furthermore, whereas being pined with three days hunger, he maketh no haste to receive meat until he be baptized, thereby appeareth the earnest [4] desire he had to learn, because he refreshed not his body with meat until his soul had received strength.

As it had been scales - ὡσεὶ λεπίδες hōsei lepides. The word ὡσεὶ hōsei, "as it had been," is designed to qualify the following word. It is not said that scales literally fell from his eyes, but that an effect followed as if scales had been suddenly taken off. Evidently, the expression is deigned to mean no more than this. The effect was such as would take place if some dark, imperious substance had been placed before the eyes, and had been suddenly removed. The cure was as sudden, the restoration to sight was as immediate, as if such an interposing substance had been suddenly removed. This is all that the expression fairly implies, and this is all that the nature of the case demands. As the blindness had been caused by the natural effect of the light, probably on the optic nerve (Acts 9:8-9, note), it is manifest that no literal removing of scales would restore the vision. We are therefore to lay aside the idea of literal scales falling to the earth. No such thing is affirmed, and no such thing would have met the case. The word translated "scales" is used nowhere else in the New Testament. It means properly "the small crust or layer which composes a part of the covering of a fish, and also any thin layer or leaf exfoliated or separated, as scales of iron, bone, or a piece of bark, etc." (Webster). An effect similar to this is described in Tobit 11:8, 13. It is evident that there was a miracle in the healing of Saul. The "blindness" was the natural effect of the light. The "cure" was by miraculous power. This is evident:
(1) Because there were no means used that would naturally restore the sight. It may be remarked here that "gutta serena" has been regarded by physicians as one of the most incurable of diseases. Few cases are restored, and few remedies are efficacious (See the Edinburgh Encyclopedia's "Surgery" on Amaurosis.)
(2) Ananias was sent for this very purpose to heal him, Acts 9:17.
(3) the immediate effect shows that this was miraculous. Had it been a slow recovery, it might have been doubtful; but here it was instantaneous, and it was thus put beyond a question that it was a miracle.
And was baptized - In this he followed the example of all the early converts to Christianity. They were baptized immediately. See Acts 2:41; Acts 8:12, Acts 8:36-39.

There fell from his eyes as it had been scales - This was real: he had been so dazzled with the brightness of the light that we may suppose the globe of the eye, and particularly the cornea, had suffered considerable injury. The structure of the cornea was doubtless much disturbed, and the whole of that humor would be rendered opaque, and incapable of permitting the rays of light to pass through the different humours to the retina, where all the images of things transmitted through the lenses, or humours, are distinctly painted. In the miraculous cure the membrane was restored to its primitive state, and the opaque matter separated from the cornea, in the form of thin laminae or scales. This being done, the light would have as free a passage as formerly, and the result would be distinct vision.
And arose, and was baptized - That he was baptized by Ananias there is every reason to believe; as he appears to have been the chief Christian at Damascus. As baptism implied, in an adult, the public profession of that faith into which he was baptized, this baptism of Saul proved, at once, his own sincerity, and the deep and thorough conviction he had of the truth of Christianity.

And immediately there fell from his eyes, as it had been scales,.... Which were little thin skins or films, like the scales of fishes, which were formed from the defluxions that fell from his brain, through the excessive light that shone around him, and the surprise he was thrown into by it: these, as soon as Ananias put his hands upon him, dropped off; which were an emblem and representation of the scales of ignorance, of himself, of sin, of righteousness, of the law, of the Gospel, and of Jesus as the Messiah; and of unbelief in him, and of pride, malice, and envy, and of superstition and bigotry, and of error and false doctrine, which, upon his being enlightened by the Spirit of God, fell from him:
and he received sight forthwith; his corporeal sight, which was an emblem of that spiritual sight he had also received: the word "forthwith", or "immediately", is not in the Vulgate Latin, Syriac, and Arabic versions, but seems necessary; and indeed, if it was not expressed, it would be understood; for as soon as the scales fell from his eyes, he must receive his sight: the Ethiopic version places it after the word "baptized", in the next clause:
and arose, and was baptized; that is, after Ananias had appointed it to him, as his duty, had pressed him to it, and called upon him to submit to it without delay, Acts 22:16 And this shows that baptism was performed by immersion; for had it been done in any other way, either by pouring or sprinkling a little water, Saul might have kept his seat, and water might have been brought to him, and so the ordinance might have been performed; but he arose and went, either to a bath that might be in Judas's house, fit for such a purpose; for the Jews had their baths to bathe their whole bodies in on certain occasions; or he went to some certain place of water without doors, convenient for the administration of baptism, where it was administered by Ananias unto him. And this also may suggest to us, that only enlightened persons are the proper objects of this ordinance; such as have the scales of darkness, ignorance, and unbelief removed from them, and have a spiritual sight and sense of divine things: hence the ancients used to call baptism by the name of "illumination", and baptized persons "enlightened" ones.

there fell from his eyes as it were scales--"This shows that the blindness as well as the cure was supernatural. Substances like scales would not form naturally in so short a time" [WEBSTER and WILKINSON]. And the medical precision of Luke's language here is to be noted.
was baptized--as directed by Ananias (Acts 22:16).

He arose, and was baptized. The account is more fully given by Paul himself (Acts 22:13-16). Ananias said, "Receive thy sight, and in the same hour I looked upon him." Then, after stating why the Lord had called him, he added: "Why tarriest thou? Arise, and be baptized, and wash away thy sins, calling on the name of the Lord." Note (1) that "tarrying" for weeks or months before baptism was then unknown; (2) that there would be no necessity of "arising," if water was applied in baptism, but there would be if he had to go to a place suitable for immersion; (3) that the term wash (Greek, "bathe") implies more than a sprinkling or pouring; (4) that neither Ananias nor Paul (Acts 22:16) understood that his sins were remitted before baptism. Compare Acts 2:38 and Acts 22:16.
