[2.] What meaneth, “to prove him”? Did not He know what would be said by him? We cannot assert that. What then is the meaning of the expression? We may discover it from the Old [Testament]. For there too it is said, “And it came to pass after these things that God did tempt Abraham, and said unto him, Take thy beloved son whom thou lovest” ( Gen. xxii. 1, 2 ); yet it doth not appear in that place either, that when He saith this He waited to see the end of the trial, whether Abraham would obey or not, (how could He, who knoweth all things before they come into existence? but the words in both cases are spoken after the manner of men. For as when (the Psalmist) saith that He “searcheth the hearts of men,” he meaneth not a search of ignorance but of exact knowledge, just so when the Evangelist saith that He proved (Philip), he meaneth only that He knew exactly. And perhaps one might say another thing, that as He once made Abraham more approved, so also did He this man, bringing him by this question to an exact knowledge of the miracle. The Evangelist therefore, that thou mayest not stop at the feebleness of the expression, and so form an improper opinion of what was said, addeth, “He Himself knew what He would do.”
