כֵּ֣ן יִנְהַ֣ג מֶֽלֶךְ־אַ֠שּׁוּר אֶת־שְׁבִ֨י מִצְרַ֜יִם וְאֶת־גָּל֥וּת כּ֛וּשׁ נְעָרִ֥ים וּזְקֵנִ֖ים עָר֣וֹם וְיָחֵ֑ף וַחֲשׂוּפַ֥י שֵׁ֖ת עֶרְוַ֥ת מִצְרָֽיִם׃
Así llevará el rey de Asiria la cautividad de Egipto y la transmigración de Etiopía, de mozos y de viejos, desnuda y descalza, y descubiertas las nalgas para vergüenza de Egipto.
Rashi
three years shall he go in this manner as a sign and a symbol for Egypt and for Cush, that, at the end of three years the king of Assyria shall lead the captivity of Egypt... We learn that Tartan conquered Ashdod three years prior to the downfall of Sennacherib, for his downfall was when he brought the captives of Egypt and Tirhakah the king of Cush before Jerusalem in chains, when he came to besiege Hezekiah.
Rashi
in half up to their groin - Heb. הַמִפְשָׂעָה, up to their private parts, both front and back, and in Samuel (II 10:4): “שְׁתוֹתֵיהֶם, their private parts,” like (Isa. 20:4): “... with their private parts (שֵׁת) bared, the shame of Egypt.”
Rashi
ויקח שם ויפת AND SHEM AND JAPHETH TOOK — (literally, “And Shem took and Japheth”) It is not written here ויקחו ‘‘And they took”, but ויקח “And he took”, in order to teach regarding Shem that he devoted himself to this duty with more eagerness than Japheth. Therefore have Shem’s sons received the privilege of wearing the cloak that has fringes, and the sons of Japheth were privileged to receive honorable burial, as it is said, (Ezekiel 39:11) “I will give unto Gog (a descendant of Japheth) a place fit for burial [in Israel]”. But as for Ham who despised his father — of his descendants it is said (Isaiah 20:4) “So shall the king of Assyria lead away the captives of Egypt, and the exiles of Ethiopia (these were peopled by the children of Ham) young and old, naked and barefoot and with buttocks uncovered etc.” (Genesis Rabbah 36:6 and Tanchuma 1:2:15).
