Tehillim 105:19 Kabbala: Zohar

"Then Pharaoh sent and called Joseph." It should have been written "to call Joseph". It was the Holy One, blessed be He, (who called) as it is written, "until the time that His word came to pass, the word of Hashem had tested him" (Tehilim 105:19). The verse, "until the time that His word came to pass" is similar to the phrase, "and called Joseph". It is written here "and called Joseph" and elsewhere "And He called to Moses" (Vayikra 1:1). "And he shaved himself, and changed his garments" out of respect for the king.
