When Joseph was taken down to Egypt, Potiphar, a courtier of Pharaoh and his prefect—an Egyptian—bought him from the Ishmaelites who had brought him there.
English: “And Yosef was brought down to Mitzrayim” — R’ Elazar said: do not read “was brought down” but “he brought down,” for he brought down Pharaoh’s astrologers from their greatness.
On the daf / in context: Yosef’s descent is read as the eventual lowering of Egyptian magical prestige when he alone interprets dreams correctly.
Type of Learning
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. A vowel/reading shift turns passive exile into active historical consequence.
What Is Learned
Yosef’s arrival in Mitzrayim is the beginning of the fall of Pharaoh’s astrologers from power.
