אַךְ־בְּזֹ֖את נֵא֣וֹת לָכֶ֑ם אִ֚ם תִּהְי֣וּ כָמֹ֔נוּ לְהִמֹּ֥ל לָכֶ֖ם כָּל־זָכָֽר׃
Only on this condition will we consent unto you: if ye will be as we are, that every male of you be circumcised;
Rashi on Genesis
נאות לכם means WE WILL CONSENT UNTO YOU: it has the same meaning as (2 Kings 12:9) ויאותו “and they consented”.
Siftei Chakhamim
Will we be reconciled with you. Rashi is saying that נאות does not mean נויה (beauty) or נאוה (habitation). For if so, in v. 22 it should not have written יאותו לנו but ינאו לנו, which is the correct conjugation for נוי.
