Observe, 1. The delay of Joseph's enlargement. It was not till the end of two full years (Gen 41:1); so long he waited after he had entrusted the chief butler with his case and began to have some prospect of relief. Note, We have need of patience, not only bearing, but waiting, patience. Joseph lay in prison until the time that his word came, Psa 105:19. There is a time set for the deliverance of God's people; that time will come, though it seem to tarry; and, when it comes, it will appear to have been the best time, and therefore we ought to wait for it (Hab 2:3), and not think two full years too long to continue waiting. 2. The means of Joseph's enlargement, which were Pharaoh's dreams, here related. If we were to look upon them as ordinary dreams, we might observe from them the follies and absurdities of a roving working fancy, how it represents to itself tame cows as beasts of prey (nay, more ravenous than any, eating up those of their own kind), and ears of corn as devouring one another. Surely in the multitude of dreams, nay, even in one dream, there are divers vanities, Ecc 5:7. Now that God no longer speaks to us in that way, I think it is no matter how little we either heed them or tell them. Foolish dreams related can make no better than foolish talk. But these dreams which Pharaoh dreamed carried their own evidence with them that they were sent of God; and therefore, when he awoke, his spirit was troubled, Gen 41:8. It cannot but put us into a concern to receive any extraordinary message from heaven, because we are conscious to ourselves that we have no reason to expect any good tidings thence. His magicians were puzzled, the rules of their art failed them: these dreams of Pharaoh, it seems, did not fall within the compass of them, so that they could not offer at the interpretation of them. This was to make Joseph's performance by the Spirit of God the more admirable. Human reason, prudence, and foresight, must be nonplussed, that divine revelation may appear the more glorious in the contrivance of our redemption, Co1 2:13, Co1 2:14. Compare with this story, Dan 2:27; Dan 4:7; Dan 5:8. Joseph's own dreams were the occasion of his troubles, and now Pharaoh's dreams were the occasion of his enlargement.

Called for all the magicians - חרטמים chartummim. The word here used may probably mean no more than interpreters of abstruse and difficult subjects; and especially of the Egyptian hieroglyphics, an art which is now entirely lost. It is most likely that the term is Egyptian, and consequently its etymology must remain unknown to us. If Hebrew, Mr. Parkhurst's definition may be as good as any: "חרט cheret, a pen or instrument to write or draw with, and תם tam, to perfect or accomplish; those who were perfect in drawing their sacred, astrological, and hieroglyphical figures or characters, and who, by means of them, pretended to extraordinary feats, among which was the interpretation of dreams. They seem to have been such persons as Josephus (Ant., lib. ii., c. 9, s. 2) calls Ἱερογραμματεις sacred scribes, or professors of sacred learning."
Wise men - חכמיה chacameyha, the persons who, according to Porphyry, "addicted themselves to the worship of God and the study of wisdom, passing their whole life in the contemplation of Divine things. Contemplation of the stars, self-purification, arithmetic, and geometry, and singing hymns in honor of their gods, was their continual employment." - See Dodd. It was probably among these that Pythagoras conversed, and from whom he borrowed that modest name by which he wished his countrymen to distinguish him, viz., φιλοσοφος, a philosopher, simply, a lover of wisdom.

And it came to pass in the morning, that his spirit was troubled,.... With the thoughts of his dreams; they were uppermost in his mind; he was continually thinking of them; it was as if he had always the same images before him now awake, as well as when asleep, and therefore could not be easy without getting knowledge of the meaning of them:

and he sent and called for all the magicians of Egypt, and all the wise men thereof; who pretended to have great skill in the things of nature, and in astrology and other sciences, by which they pretended to know future events, and to interpret dreams among other things; and show what they portended, and what things would happen for the accomplishment of them:

and Pharaoh told them his dream; both his dreams, which for the similarity of them, and there being so little interruption between them, are represented as one dream; for that both were told them appears by what follows:

but there was none that could interpret them unto Pharaoh; they were nonplussed and confounded, and did not know what to say; the things were so strange and surprising that he related, that they could not offer any conjectures about them, or, if they did, they were very unsatisfactory to Pharaoh.

he called for all the magicians of Egypt--It is not possible to define the exact distinction between "magicians" and "wise men"; but they formed different branches of a numerous body, who laid claim to supernatural skill in occult arts and sciences, in revealing mysteries, explaining portents, and, above all, interpreting dreams. Long practice had rendered them expert in devising a plausible way of getting out of every difficulty and framing an answer suitable to the occasion. But the dreams of Pharaoh baffled their united skill. Unlike their Assyrian brethren (Dan 2:4), they did not pretend to know the meaning of the symbols contained in them, and the providence of God had determined that they should all be nonplussed in the exercise of their boasted powers, in order that the inspired wisdom of Joseph might appear the more remarkable.
