וְעַתָּ֗ה לֹֽא־אַתֶּ֞ם שְׁלַחְתֶּ֤ם אֹתִי֙ הֵ֔נָּה כִּ֖י הָאֱלֹהִ֑ים וַיְשִׂימֵ֨נִֽי לְאָ֜ב לְפַרְעֹ֗ה וּלְאָדוֹן֙ לְכָל־בֵּית֔וֹ וּמֹשֵׁ֖ל בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃
So now it was not you that sent me hither, but God; and He hath made me a father to Pharaoh, and lord of all his house, and ruler over all the land of Egypt.
Rashi on Genesis
לאב A FATHER — he made me his colleague and he bestowed on me the dignity of “Father of the king.”
Sforno on Genesis
ועתה לא אתם שלחתם, now that you have seen G’d’s purpose a purpose that could not have been achieved without all the various stages preceding it, it is no more than reasonable to suppose that also the further distant causes which led up to all this were part of G’d’s plan.
