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.

Two full years - שנתים ימים shenathayim yamim, two years of days, two complete solar revolutions, after the events mentioned in the preceding chapter.

The river - The Nile, the cause of the fertility of Egypt.

And it came to pass at the end of two full years,.... It is not a clear case, as Aben Ezra observes, from whence these years are to be reckoned, whether from the time of Joseph's being put into prison, or from the time that the chief butler was taken out of it; the latter seems more probable, and better connects this and the preceding chapter:

that Pharaoh dreamed, and, behold, he stood by the river; it seemed to him, in his dream, as if he stood near the river Nile, or some canal or flow of water cut out of that river.
