The Sea of Gaza

I just came across an interesting angle on the pejorative suggestion to "drink from the Sea of Gaza". Mordechai Akiva Friedman published a ketubba written in "Hazor de'al gaf Yama demeliha", Hasor, which is on the shore of the salty sea. He shows (Jewish Marriage in Palestine II, Tel Aviv 1981, pp. 316-317) that this is Rafiah, and that "the salty sea" is the accepted name for the Mediterranean.
