וַיְמָאֵ֓ן ׀ וַיֹּ֙אמֶר֙ אֶל־אֵ֣שֶׁת אֲדֹנָ֔יו הֵ֣ן אֲדֹנִ֔י לֹא־יָדַ֥ע אִתִּ֖י מַה־בַּבָּ֑יִת וְכֹ֥ל אֲשֶׁר־יֶשׁ־ל֖וֹ נָתַ֥ן בְּיָדִֽי׃
Ale on wzbraniał się, i rzekł do żony pana swojego: "Oto pan mój nie troszczy się przy mnie o nic, co w domu, a wszystko, co posiada, oddał w ręce moje.
Ramban on Genesis
BUT HE REFUSED, AND SAID UNTO HIS MASTER’s WIFE. Scripture relates that he refused to do her will even though she was his mistress, i.e., his master’s wife, and he feared her, for he feared G-d more. This is the meaning of the expression, unto his master’s wife.
Haamek Davar on Genesis
But he refused. The verse testifies that he, without any reasoning, refused to turn his cohabitation into fornication, but that he was forced to give his master's wife ulterior reasons apart from this.
