Here, I. Joseph relates the prophetical dreams he had, Gen 37:6, Gen 37:7, Gen 37:9, Gen 37:10. Though he was now very young (about seventeen years old), yet he was pious and devout, and well-inclined, and this fitted him for God's gracious discoveries of himself to him. Joseph had a great deal of trouble before him, and therefore God gave him betimes this prospect of his advancement, to support and comfort him under the long and grievous troubles with which he was to be exercised. Thus Christ had a joy set before him, and so have Christians. Note, God has ways of preparing his people beforehand for the trials which they cannot foresee, but which he has an eye to in the comforts with which he furnishes them. His dreams were, 1. That his brethren's sheaves all bowed to his, intimating upon what occasion they should be brought to do homage to him, namely, in seeking to him for corn; their empty sheaves should bow to his full one. 2. That the sun, and moon, and eleven stars, did obeisance to him, Gen 37:9. Joseph was more of a prophet than a politician, else he would have kept this to himself, when he could not but know that his brethren did already hate him and that this would but the more exasperate them. But, if he told it in his simplicity, yet God directed it for the mortification of his brethren. Observe, Joseph dreamed of his preferment, but he did not dream of his imprisonment. Thus many young people, when they are setting out in the world, think of nothing but prosperity and pleasure, and never dream of trouble.
II. His brethren take it very ill, and are more and more enraged against him (Gen 37:8): Shalt thou indeed reign over us? See here, 1. How truly they interpreted his dream, that he should reign over them. Those become the expositors of his dream who were enemies to the accomplishment of it, as in Gideon's story (Jdg 7:13, Jdg 7:14); they perceived that he spoke of them, Mat 21:45. The event exactly answered to this interpretation, Gen 42:6, etc. 2. How scornfully they resented it: "Shalt thou, who are but one, reign over us, who are many? Thou, who are the youngest, over us who are older?" Note, The reign and dominion of Jesus Christ, our Joseph, have been, and are, despised and striven against by a carnal and unbelieving world, who cannot endure to think that this man should reign over them. The dominion also of the upright, in the morning of the resurrection, is thought of with the utmost disdain.
III. His father gives him a gentle rebuke for it, yet observes the saying, Gen 37:10, Gen 37:11. Probably he checked him for it, to lessen the offence which his brethren would be apt to take at it; yet he took notice of it more than he seemed to do: he insinuated that it was but an idle dream, because his mother was brought in, who had been dead some time since; whereas the sun, moon, and eleven stars, signify no more than the whole family that should have a dependence upon him, and be glad to be beholden to him. Note, The faith of God's people in God's promises is often sorely shaken by their misunderstanding the promises and then suggesting the improbabilities that attend the performance; but God is doing his own work, and will do it, whether we understand him aright or no. Jacob, like Mary (Luk 2:51), kept these things in his heart, and no doubt remembered them long afterwards, when the event answered to the prediction.

He dreamed yet another dream - This is as clear as the preceding. But how could Jacob say, Shall I and thy mother, etc., when Rachel his mother was dead some time before this? Perhaps Jacob might hint, by this explanation, the impossibility of such a dream being fulfilled, because one of the persons who should be a chief actor in it was already dead. But any one wife or concubine of Jacob was quite sufficient to fulfill this part of the dream. It is possible, some think, that Joseph may have had these dreams before his mother Rachel died; but were even this the case, she certainly did not live to fulfill the part which appears to refer to herself.
The sun and the moon and the eleven stars - Why eleven stars? Was it merely to signify that his brothers might be represented by stars? Or does he not rather there allude to the Zodiac, his eleven brethren answering to eleven of the celestial signs, and himself to the twelfth? This is certainly not an unnatural thought, as it is very likely that the heavens were thus measured in the days of Joseph; for the zodiacal constellations have been distinguished among the eastern nations from time immemorial. See Clarke at Gen 49:33 (note).

And his brethren envied him,.... Notwithstanding all the precaution Jacob took to prevent it; they suspecting and fearing that these dreams portended the pre-eminence of Joseph over them, or however served to fill his mind with the hopes and expectation of it:

but his father observed the saying; what Joseph had said in relating his dream; he laid it up in his mind and kept it there, often thought of it, and waited to see its accomplishment.

THE DREAMS OF JOSEPH. (Gen. 37:5-36)

Joseph dreamed a dream--Dreams in ancient times were much attended to, and hence the dream of Joseph, though but a mere boy, engaged the serious consideration of his family. But this dream was evidently symbolical. The meaning was easily discerned, and, from its being repeated under different emblems, the fulfilment was considered certain (compare Gen 41:32), whence it was that "his brethren envied him, but his father observed the saying" [Gen 37:11].
