John Chrysostom
This proposal was both reasonable and fitting; however, it was presented "with guile," as stated in Scripture.
We cannot do what you demand, nor give our sister to one that is uncircumcised; which with us is unlawful and abominable.
וַיֹּאמְר֣וּ אֲלֵיהֶ֗ם לֹ֤א נוּכַל֙ לַעֲשׂוֹת֙ הַדָּבָ֣ר הַזֶּ֔ה לָתֵת֙ אֶת־אֲחֹתֵ֔נוּ לְאִ֖ישׁ אֲשֶׁר־ל֣וֹ עָרְלָ֑ה כִּֽי־חֶרְפָּ֥ה הִ֖וא לָֽנוּ׃
