This, and what follows in this and the two next verses, are not in any of the former accounts; and these words are used not only because Saul was fallen to the earth, and are an encouragement to rise up, and stand corporeally, but to take heart, and be of good cheer; for though he had acted so vile and cruel a part by Christ, and his people, yet he had designs of grace, and good will to him; and this appearance was not for his destruction, but for his honour, comfort, and usefulness:for I have appeared unto thee for this purpose; not to take vengeance for past offences, but for the ends hereafter mentioned: and this appearance of Christ was real, corporeal, and personal, and not imaginary, or merely visionary and intellectual; and it was to this sight of Christ he more than once refers, partly in proof of Christ's resurrection from the dead, and partly to demonstrate the truth of his apostleship, 1Co 9:1.
