Talmud for Ketubot 3:7
אֵיזוֹהִי בֹשֶׁת, הַכֹּל לְפִי הַמְבַיֵּשׁ וְהַמִּתְבַּיֵּשׁ. פְּגָם, רוֹאִין אוֹתָהּ כְּאִלּוּ הִיא שִׁפְחָה נִמְכֶּרֶת, כַּמָּה הָיְתָה יָפָה וְכַמָּה הִיא יָפָה. קְנָס, שָׁוֶה בְכָל אָדָם. וְכֹל שֶׁיֶּשׁ לוֹ קִצְבָּה מִן הַתּוֹרָה, שָׁוֶה בְכָל אָדָם:
Which is bosheth (shame)? All according to the one who shames and the one who is shamed. [The bosheth of a common man who shames is greater than that of a lowly one or of a distinguished one. Thus did I find it in the glosses of my rabbis. And in Hachovel (Bava Kamma), I found that the bosheth of a lowly man is greater, and this is the essential interpretation. ("and the one who is shamed":) His bosheth is proportionate to his eminence.] (Which is) p'gam (injury)? We perceive her as a bondswoman to be sold. How much would she be worth, and how much is she worth (now). [We assess how much more a man would want to give to marry a virgin bondswoman to a favored bondsman than one who is not a virgin. The gemara asks how we know that one gives bosheth, p'gam, and tza'ar. Perhaps the Torah ordains the fifty kesef to cover everything. And it answers that we derive it from (Deuteronomy 22:29): "Then the man who lies with her shall give the father of the maiden fifty kesef" — the enjoyment of "lying" alone is fifty kesef, aside from bosheth, p'gam, and tza'ar.] Knass is the same for all men. Anything which has a fixed amount in the Torah is the same for all men.
