Gen 37:20

“And in Genesis they also said, "And we shall see what will become of his dreams." This is written in regard to Joseph, but it is fulfilled in regard to Christ, when the Jews said in the course of his passion, "If he is the King of Israel, let him come down now from the cross, and we will believe him. He trusts in God; let him deliver him now, if he wants him." But were those brothers so unholy as to kill their brother? And from what source do the merits of the mighty patriarchs derive, so that the law designates the tribes of the entire people by their names? How are names of holiness in accord with marks of crime? In this also they served as a model of the people; their own souls were not toiling under a burden of crime. This gave rise to all the enmity and the plotting of fratricide; the enmity is by way of figure, the holiness by way of love.”

“ונראה מה יהיו חלמתיו AND WE SHALL SEE WHAT WILL BECOME OF HIS DREAMS — R. Isaac said, this verse calls for a homiletic explanation. The Holy Spirit said this latter part of the text. They say “let us slay him”, and Scripture (i.e. the Holy Spirit) breaks in upon their words concluding them by saying, “and we shall see what will become of his dreams”: we shall see whose words will be fulfilled — yours or mine. For it is impossible that they should have said, “and we shall see what will become of his dreams”, for as soon as they would kill him his dreams would be of no effect (Tanchuma Yashan 1:9:13).”

“AND WE SHALL SEE WHAT WILL BECOME OF HIS DREAMS. This is a derisive metaphor: “We shall see after his death if we shall prostrate ourselves before him.” The correct interpretation appears to me to be that they said, “Now we shall see what will become of his dreams, for if he shall be rescued from our hands he will surely reign over us.” But our Rabbis said: “It is the Ruach Hakodesh, Note 90. that says, We shall see what will become of his dreams, which completes the sentence, and not Joseph’s brothers. as if to say; ‘We shall see whose words shall stand, Mine or theirs.’””
