וַתֹּ֨אמֶר שָׂרַ֣י אֶל־אַבְרָם֮ חֲמָסִ֣י עָלֶיךָ֒ אָנֹכִ֗י נָתַ֤תִּי שִׁפְחָתִי֙ בְּחֵיקֶ֔ךָ וַתֵּ֙רֶא֙ כִּ֣י הָרָ֔תָה וָאֵקַ֖ל בְּעֵינֶ֑יהָ יִשְׁפֹּ֥ט יְהוָ֖ה בֵּינִ֥י וּבֵינֶֽיׄךָ׃
האָט שָׂרַי געזאָגט צו אבֿרמען: מײַן עװלה אױף דיר! איך האָב געגעבן מײַן דינסט אין דײַן בוזעם, און װי זי האָט געזען אַז זי איז טראָגעדיק, אַזױ בין איך גרינגעשאַצט געװאָרן אין אירע אױגן; זאָל גאָט משפּטן צװישן מיר און צװישן דיר.
Rashi
חמסי עליך MY WRONG BE UPON THEE — The wrong done to me (חמסי)— the punishment for it I call down on you (עליך). “When you prayed to the Holy One, blessed be He, (15:2) ‘what wilt Thou give me, seeing that I go childless’, you prayed only on behalf of yourself whereas you should have prayed on behalf of both of us — then would I have been borne in mind (by God) together with you” (i.e. when you had the gift of a child it would have been “my” child also — not that of a strange woman). Besides this, you deprive me (חומס) of your protecting words since you hear how I am despised and yet you keep silent (Genesis Rabbah 45:5).
Chizkuni
חמסי, “look at what reward I get that my own maidservant refuses to obey my commands, and acts rebelliously.
Sforno
חמסי עליך, "you should have rebuked her for her conduct vis-à-vis me, seeing that she has become your wife [and you are now her boss instead of me. Ed.] She treats me as inconsequential after she has become pregnant from you."
