Why is there a double expression "ve'Lo Zachar... va'Yishkachehu"?
Rashi, Rashbam and Targum Yonasan: He did not remember 1 him on the day that he was released, and he forgot him subsequently, until his punishment was completed (and until Hashem performed miracles on behalf of Yosef and he was needed
Riva, Hadar Zekenim: Even though he was a Rasha, the verse teaches that he was Shogeg, for his merit. All the more so for Tzadikim [the Torah advocates for them]!
Oznayim la'Torah: Had Pharaoh released him now, he would not have subsequently known where he was. In fact, he would probably have returned home to his father.
What did Yosef do to deserve remaining in jail two more years (as the Pasuk states at the beginning of Vayigash)?
Rashi: He placed his faith in an Egyptian (Tehilim 40:5), whom the Pasuk (Yeshayah 30:7) refers to as arrogant. 1
Targum Yonasan: He placed his faith in a human being and not in Hashem. 2
Midrash Rabah (89:3): Two years were added due to his two requests of the butler to remember him.
As the Pasuk says in Yirmiyah (17:5) "Arur ha'Gever asher Yivtach ba'Adam... " (Targum Yerushalmi). Refer also to 43:9:4:1**.
