Charles Ellicott Commentary Acts 9:18

"And straightway there fell from his eyes as it were scales, and he received his sight; and he arose and was baptized;" — Acts 9:18 (ASV)

There fell from his eyes as it had been scales.—The description suggests that the blindness was caused by an incrustation, caused by acute inflammation, covering the pupil of the eye, or closing up the eyelids, analogous to the “whiteness,” that peeled (or scaled) off from the eyes of Tobit . Similar phenomena are mentioned by Hippocrates, and the care with which St. Luke records the fact in this instance, may be noted, with Acts 3:7; Acts 28:8, as one of the examples of the technical precision of his calling as a physician.

Arose, and was baptised.—It is clear that both Saul and Ananias looked on this as the indispensable condition for admission into the visible society of the kingdom of God. No visions and revelations of the Lord, no intensity of personal conversion, exempted him from it. For him, too, that was the washing of regeneration (Titus 3:5), the moment of the new birth, of being buried with Christ (Romans 6:3–4). It may be inferred almost as a matter of certainty that it was at the hands of Ananias that he received baptism. The baptism would probably be administered in one or other of the rivers which the history of Naaman had made famous, and so the waters of Abana and Pharpar, rivers of Damascus (2 Kings 5:12), were now sanctified no less than those of Jordan for the mystical washing away of sin.
