Midrasch zu Bereschit 44:27

Said R. Juda in the name of Rab: "Why was Joseph called bones while yet alive?" Because he did not protest when the honor of his father was disparaged. For, his brothers said to him (Gen. 44, 27) And thy servant our father said, "and he did not protest in the least." R. Juda said again in the name of R. Chama b. Chanina: "Why did Joseph die before his brothers? Because he assumed airs of superiority." (Gen. 39, 1) And Joseph was brought down to Egypt. Said R. Elazar: "Do not read Horad (that he was brought down) but read Horid (he caused to bring down others) i.e., he caused the removal of the astrologers of Egypt from their high positions."
