ציטירנדיקער פּירוש אויף שמואל א 15:5

And Midianite men passed There are commentaries that the Midianites heard him screaming in the pit, and brought him up, and kidnapped him, and sold him to Yishmaelites for twenty pieces of silver, and made a great profit from this since they hadn't spent anything on him. The Yishmaelites then brought him down to Egypt, and what it says at the end of the parsha, "And the Midianites sold him to Egypt..." (Bereishit 37:36), is that they sold him in order to bring him down to Egypt, and this is not just lies! For behild, it's written there "to Potifar", and further, that in that place it's difficult why he didn't reveal himself. And also, there is one who says Madanim [מדנים] and Midaynim [מדיינים], [called this] for the name of the cargo that they carry, such as in Iyov 38:31 "Can you bind the cords [ma'adnot; מַעֲדַנּוֹת] of the Pleiades?", or I Samuel 15:32 "And Agag came to him in chains [ma'adnot; מַעֲדַנּוֹת]". And sometimes the ayin is omitted, for it's usual to omit the letters alef, chet, hey and ayin. For example, "and laid in wait [vayarev, וַיָּרֶב] in a valley" (I Samuel 15:5), which is like vaye'arev ויארב. And so too is explained "sitters on couches [midin, מִדִּין]" (Shoftim 5:10), that it's like on the cargo which is bound. And all of this isn't worth anything to me, but it was one people, as I have explained, just as they call us sometimes Yehudim and sometimes Yisra'elim and sometimes Yeshurun. And the truth is that his brothers sold him, as he said to them "that have sold me here" (Bereishit 45:4), and [the merchants?] caused them to swear, as I have explained, and made from them great profit, like a man who sells his field because of its poor quality, for they would give of their own that someone would distance it from them, for in they end they hated him with a hatred.
