5:3,4 In these lay a great multitude. All that follows the word withered in the third verse and all the fourth are wanting in the best MSS, and are evidently an interpolation.
5:4 An angel - Yet many undoubtedly thought the whole thing to be purely natural. At certain times - Perhaps at a certain hour of the day, during this paschal week, went down - The Greek word implies that he had ceased going down, before the time of St. John's writing this. God might design this to raise expectation of the acceptable time approaching, to add a greater lustre to his Son's miracles, and to show that his ancient people were not entirely forgotten of him. The first - Whereas the Son of God healed every day not one only, but whole multitudes that resorted to him.
5:1-9 We are all by nature impotent folk in spiritual things, blind, halt, and withered; but full provision is made for our cure, if we attend to it. An angel went down, and troubled the water; and what disease soever it was, this water cured it, but only he that first stepped in had benefit. This teaches us to be careful, that we let not a season slip which may never return. The man had lost the use of his limbs thirty-eight years. Shall we, who perhaps for many years have scarcely known what it has been to be a day sick, complain of one wearisome night, when many others, better than we, have scarcely known what it has been to be a day well? Christ singled this one out from the rest. Those long in affliction, may comfort themselves that God keeps account how long. Observe, this man speaks of the unkindness of those about him, without any peevish reflections. As we should be thankful, so we should be patient. Our Lord Jesus cures him, though he neither asked nor thought of it. Arise, and walk. God's command, Turn and live; Make ye a new heart; no more supposes power in us without the grace of God, his distinguishing grace, than this command supposed such power in the impotent man: it was by the power of Christ, and he must have all the glory. What a joyful surprise to the poor cripple, to find himself of a sudden so easy, so strong, so able to help himself! The proof of spiritual cure, is our rising and walking. Has Christ healed our spiritual diseases, let us go wherever he sends us, and take up whatever he lays upon us; and walk before him.
