וּמֶ֥לֶךְ אֵ֛ין בֶּאֱד֖וֹם נִצָּ֥ב מֶֽלֶךְ׃
E in Edom non vi era re; un governatore fungeva da re.
Rabbeinu Bahya
והנה אנחנו מאלמים אלומים וגו, “and here we were binding sheaves, etc.” They realised in their wisdom that the meaning of the dream was that the sheaves bowing to Joseph’s sheaf meant that he viewed himself as enjoying Royal authority. over them. This feeling of theirs was reinforced by his use of the words נצבה, an expression which is associated with Royalty such as in Kings I 22,48 נצב המלך, ”he acted as king.” It was because they were aware of this interpretation of his dream that they said to Joseph sarcastically: “are you planning to rule over us as a king?” What the brothers were not aware of was the fact that Joseph’s eventual appointment as king would be triggered by the subject of corn harvests (i.e. his prediction of abundance of such harvests and subsequent failure of such harvests).
Seeing that they hated Joseph already it is quite understandable that they interpreted his nocturnal dreams as boding no good for them instead of seeing the positive element that might be presaged by such dreams. Actually, even their interpretation of Joseph’s dreams was inspired by G’d who caused them to verbalise such thoughts. This is reminiscent of something we read in connection with Gideon (Judges 7,10) to whom G’d had said that in preparation for his battle against the Midianites and in order to reassure him, he should go down amongst the camp of the Midianites and listen to what they had to say. Gideon did so and overheard a Midianite soldier tell his companion that he had dreamt that there was a commotion; a loaf of barley bread was whirling through the Midianite camp. It came to a tent, struck it, and the tent collapsed and turned upside down and collapsed. To this his companion responded: “this can only mean the sword of the Israelite Gideon son of Yoash. G’d is delivering Midian and the entire camp into his hands.” When Gideon heard the dream told and interpreted, he bowed low. (to G’d in gratitude) This was another instance when G’d inspired someone to interpret and verbalise a dream which subsequently came true. This may be the source of the Talmud saying in Berachot 58 that “all dreams are influenced by the interpretation which is being “given by the mouth,” [i.e. which has been verbalised. Ed.] Here too G’d placed the words in the mouths of the brothers so that eventually Joseph’s dreams would become true.

Rashi
In his days, Edom rebelled, etc. For David had destroyed all the males in Edom, and he appointed governors over them instead of a king, and they paid him tribute, and all the kings of Judah did similarly: they appointed governors who pleased them. And from the days of Joram and thereafter, they [the Edomites] rebelled against the authority of Judah.
Rashi
And appointed a king over themselves. From the time of Dovid they did not have a king, as it is stated, “There was no king in Edom,.”18I Melochim 22:48. [and] “And he appointed governors in Edom.”19II Shmuel 8:14. Eight kings reigned in Edom before a king reigned in Yisroel, they are listed in the Book of Bereishis.20See Bereishis 36:31-43, and Rashi there. The eight kings are listed in Bereishis Rabboh 83:2. However, Bereishis Rabboh lists Shaul as one of the eight and omits Yehorom because during Yehorom’s reign, Edom was ruled by a king. Corresponding to them, eight kings reigned in Yisroel: Ish-Boshes, Dovid, Shlomo, Rechovom, Aviyom, Asa, Yehoshophot, and Yehorom, while Edom had no king.21See above 3:9. What is written above that the king of Edom22I Melochim 22:48. went with Yehorom son of Achov, and with Yehoshophot, to war against the king of Mo’av [can be explained that] he was not a real king, but a governor, who is also referred to as a king, as it is stated, “There was no king in Edom, the governor was king.”23I.e., Yorom attacked and struck the Edomites who were near the border. The governor served instead of a king.
Rashi
’ואלה המלכים וגו AND THESE ARE THE KINGS etc. — There were eight and Jacob raised an equal number in whose days the kingdom of Esau temporarily ceased to exist, viz., Saul, Ishbosheth, David, Solomon, Rehoboam, Asa, Abiah and Jehoshaphat. For of the days of Yoram his (Jehoshaphat’s) son it is written, (2 Kings 8:20) “In his days Edom revolted from under the hand of Judah and made a king over themselves”, whereas in the days of Jehoshaphat it is written, (1 Kings 22:48) “And there was no king in Edom: a deputy was king”.
