בראשית מא:נז קבלה: זוהר

Another explanation of "the king" is that it refers to the Holy One, blessed be He, while justice refers to Joseph, "who established the land" as it is written, "And all countries (lit. 'and all the land') came to Egypt to Joseph to buy provisions" (Beresheet 41:57). Because the Holy One, blessed be He, favored Jacob, He made him governor of all the land.
