Reference for Gittin 5:1
הַנִּזָּקִין שָׁמִין לָהֶם בְּעִדִּית וּבַעַל חוֹב בְּבֵינוֹנִית, וּכְתֻבַּת אִשָּׁה בְּזִבּוּרִית. רַבִּי מֵאִיר אוֹמֵר, אַף כְּתֻבַּת אִשָּׁה בְּבֵינוֹנִית:
Damages are assessed relative to the best quality (of grain in the field) [Even though this is Torah-mandated, viz. (Exodus 22:4): "The best of his field and the best of his vineyard shall he pay," this tanna holds that Scripture speaks of the best of the field of the nizzak (the one damaged); and because of "the general good," the sages stated that the mazzik (the causer of the damage) should pay the best of his property, even if it is better than the best of the nizzak, so that men be careful not to cause damage.], and a creditor (claims) from the middle quality [For according to Scripture, he claims only from the lowest quality, viz. (Deuteronomy 24:12): "And the man who is indebted to you shall bring out to you the pledge outside," and a man is likely to bring out only the least valuable of his possessions; but because of "the general good" they mandated that a creditor claim from the middle quality, so that the door not be locked to loans.], and the kethubah of a woman (is claimed from) the lowest quality. [For "the closing of the door" is not to be feared in this instance. "For more than a man wants to marry, a woman wants to be married."] R. Meir says: The kethubah of a woman, too, (is claimed from) the middle quality. [The halachah is not in accordance with R. Meir].
