פירוש על בראשית 37:8

ועל דבריו AND FOR HIS WORDS — for the evil report about them which he used to bring to their father.

SHALT THOU INDEED REIGN OVER US? OR SHALT THOU INDEED HAVE DOMINION OVER US? Rabbi Abraham ibn Ezra explained: “Shall we voluntarily make you king over us, or will you rule over us by force?” The opinion of Onkelos appears to be more correct.⁴³Since the authority of a king is essentially the same whether he rules by consent or force, Scripture should not change the expression from malach (reign) to mashal (dominion) if the explanation of Ibn Ezra is correct. Hence Ramban prefers Onkelos’ explanation which follows. He rendered it: “Shall you be king over us or some authority ruling us?” For people prostrate themselves before both. The verse thus means, “You will never be king or any kind of authority over us.”
The meaning of the expression, And they continued to hate him still more for his dreams, and for his words, is that they hated him for the dreams and for relating the dreams to them in a boastful manner, even as it says, Hear, I pray you, this dream which I have dreamed.⁴⁴Verse 6 here.

ועל דבריו, the badmouthing. [how did the brothers find out about this? Ed.]
