And Joseph (c) dreamed a dream, and he told [it] his brethren: and they hated him yet the more.
(c) God revealed to him by a dream what should come to pass.

And Joseph dreamed a dream, and he told it his brethren,.... As a dream, in the simplicity of his heart; not understanding it, or imagining there was any meaning in it; he told it not with any design to affront them, but as an amusement, and for their diversion, there being something in it odd and ridiculous, as he himself might think:
and they hated him yet the more; not only because he had carried an ill report of them to his father, and because he loved him more than they, but still more because of this dream; the meaning of which they at once understood, though he did not, which yet they supposed he did, and that he told them it in a boasting manner, and to irritate them.

God gave Joseph betimes the prospect of his advancement, to support and comfort him under his long and grievous troubles. Observe, Joseph dreamed of his preferment, but he did not dream of his imprisonment. Thus many young people, when setting out in the world, think of nothing but prosperity and pleasure, and never dream of trouble. His brethren rightly interpreted the dream, though they abhorred the interpretation of it. While they committed crimes in order to defeat it, they were themselves the instruments of accomplishing it. Thus the Jews understood what Christ said of his kingdom. Determined that he should not reign over them, they consulted to put him to death; and by his crucifixion, made way for the exaltation they designed to prevent.

THE DREAMS OF JOSEPH. (Genesis. 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 Genesis 41:32), whence it was that "his brethren envied him, but his father observed the saying" [Genesis 37:11].

This hatred was increased when Joseph told them of two dreams that he had had: viz., that as they were binding sheaves in the field, his sheaf "stood and remained standing," but their sheaves placed themselves round it and bowed down to it; and that the sun (his father), and the moon (his mother, "not Leah, but Rachel, who was neither forgotten nor lost"), and eleven stars (his eleven brethren) bowed down before him. These dreams pointed in an unmistakeable way to the supremacy of Joseph; the first to supremacy over his brethren, the second over the whole house of Israel. The repetition seemed to establish the thing as certain (cf. Genesis 41:32); so that not only did his brethren hate him still more "on account of his dreams and words" (Genesis 37:8), i.e., the substance of the dreams and the open interpretation of them, and become jealous and envious, but his father gave him a sharp reproof for the second, though he preserved the matter, i.e., retained it in his memory (שׁמר lxx διετήρησε, cf. συνετήρει, Luke 2:19). The brothers with their ill-will could not see anything in the creams but the suggestions of his own ambition and pride of heart; and even the father, notwithstanding his partiality, was grieved by the second dream. The dreams are not represented as divine revelations; yet they are not to be regarded as pure flights of fancy from an ambitious heart, but as the presentiments of deep inward feelings, which were not produced without some divine influence being exerted upon Joseph's mind, and therefore were of prophetic significance, though they were not inspired directly by God, inasmuch as the purposes of God were still to remain hidden from the eyes of men for the saving good of all concerned.

Though he was now very young, about seventeen years old, yet he was pious and devout, and this fitted him for God's gracious discoveries 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.
