And he was three days without sight, and neither did eat nor drink.

Wesley's Notes

9:9 And he was three days - An important season! So long he seems to have been in the pangs of the new birth. Without sight - By scales growing over his eyes, to intimate to him the blindness of the state he had been in, to impress him with a deeper sense of the almighty power of Christ, and to turn his thoughts inward, while he was less capable of conversing with outward objects. This was likewise a manifest token to others, of what had happened to him in his journey, and ought to have humbled and convinced those bigoted Jews, to whom he had been sent from the sanhedrim.

Jamieson-Fausset-Brown Bible Commentary

9. And he was three days without sight, and neither did eat nor drink-that is, according to the Hebrew mode of computation: he took no food during the remainder of that day, the entire day following, and so much of the subsequent day as elapsed before the visit of Ananias. Such a period of entire abstinence from food, in that state of mental absorption and revolution into which he had been so suddenly thrown, is in perfect harmony with known laws and numerous facts. But what three days those must have been! "Only one other space of three days' duration can be mentioned of equal importance in the history of the world" [Howson]. Since Jesus had been revealed not only to his eyes but to his soul (see on [1970]Ga 1:15, 16), the double conviction must have immediately flashed upon him, that his whole reading of the Old Testament hitherto had been wrong, and that the system of legal righteousness in which he had, up to that moment, rested and prided himself was false and fatal. What materials these for spiritual exercise during those three days of total darkness, fasting, and solitude! On the one hand, what self-condemnation, what anguish, what death of legal hope, what difficulty in believing that in such a case there could be hope at all; on the other hand, what heartbreaking admiration of the grace that had "pulled him out of the fire," what resistless conviction that there must be a purpose of love in it, and what tender expectation of being yet honored, as a chosen vessel, to declare what the Lord had done for his soul, and to spread abroad the savor of that Name which he had so wickedly, though ignorantly, sought to destroy-must have struggled in his breast during those memorable days! Is it too much to say that all that profound insight into the Old Testament, that comprehensive grasp of the principles of the divine economy, that penetrating spirituality, that vivid apprehension of man's lost state, and those glowing views of the perfection and glory of the divine remedy, that beautiful ideal of the loftiness and the lowliness of the Christian character, that large philanthropy and burning zeal to spend and be spent through all his future life for Christ, which distinguish the writings of this chiefest of the apostles and greatest of men, were all quickened into life during those three successive days?

Matthew Henry's Concise Commentary

9:1-9 So ill informed was Saul, that he thought he ought to do all he could against the name of Christ, and that he did God service thereby; he seemed to breathe in this as in his element. Let us not despair of renewing grace for the conversion of the greatest sinners, nor let such despair of the pardoning mercy of God for the greatest sin. It is a signal token of Divine favour, if God, by the inward working of his grace, or the outward events of his providence, stops us from prosecuting or executing sinful purposes. Saul saw that Just One, ch. 22:14; 26:13. How near to us is the unseen world! It is but for God to draw aside the veil, and objects are presented to the view, compared with which, whatever is most admired on earth is mean and contemptible. Saul submitted without reserve, desirous to know what the Lord Jesus would have him to do. Christ's discoveries of himself to poor souls are humbling; they lay them very low, in mean thoughts of themselves. For three days Saul took no food, and it pleased God to leave him for that time without relief. His sins were now set in order before him; he was in the dark concerning his own spiritual state, and wounded in spirit for sin. When a sinner is brought to a proper sense of his own state and conduct, he will cast himself wholly on the mercy of the Saviour, asking what he would have him to do. God will direct the humbled sinner, and though he does not often bring transgressors to joy and peace in believing, without sorrows and distress of conscience, under which the soul is deeply engaged as to eternal things, yet happy are those who sow in tears, for they shall reap in joy.
