12:17י״ב:י״ז
1 א

וינגע ה' וגו'. בְּמַכַּת רָאתָן לָקָה, שֶׁהַתַּשְׁמִישׁ קָשֶׁה לוֹ (בראשית רבה):

'וינגע ה' וגו AND THE LORD PLAGUED PHARAOH etc. — He was smitten with the disease of Raathon which demands close continence (Genesis Rabbah 41:2).

2 ב

(ואת ביתו כְּתַרְגּוּמוֹ וְעַל אֱנַשׁ בֵּיתֵהּ וּמִדְרָשׁוֹ לְרַבּוֹת כֹּתָלָיו וְעַמּוּדָיו וְכֵּלָיו בְּרַשִׁ"י יָשָׁן):

ואת ביתו AND HIS HOUSE — Take it as the Targum has it: “and the people of his house”. A Midrashic explanation is: the word את is used here to imply that included in the curse were also its walls, pillars and its utensils (Midrash Tanchuma, Lech Lecha 5). The whole of this explanation of ואת ביתו is given in an old text of Rashi.

3 ג

על דבר שרי. עַל פִּי דִּבּוּרָהּ; אוֹמֶרֶת לַמַּלְאָךְ הַךְ, וְהוּא מַכֶּה;

על דבר שרי BECAUSE OF SARAI (literally, by the word of Sarai) — at her orders: she said to the angel “Smite” and he smote (Midrash Tanchuma, Lech Lecha 5).
