וַיִּתְּנֵ֨ם יְהוָ֥ה בְּיַֽד־יִשְׂרָאֵל֮ וַיַּכּוּם֒ וַֽיִּרְדְּפ֞וּם עַד־צִיד֣וֹן רַבָּ֗ה וְעַד֙ מִשְׂרְפ֣וֹת מַ֔יִם וְעַד־בִּקְעַ֥ת מִצְפֶּ֖ה מִזְרָ֑חָה וַיַּכֻּ֕ם עַד־בִּלְתִּ֥י הִשְׁאִֽיר־לָהֶ֖ם שָׂרִֽיד׃
Rashi on Joshua
מִשְׂרְפוֹת מַיִם2From the word שְׂרֵפָה, fire or burning. Thus the Targum proceeds to explain: the burning of water, מַיִם. Targum Yonasan translates, sea-ditches. They dug ditches and the sea water would flow into them, and the water would be burned [evaporate] from the heat of the sun and would turn into salt.
