Genesis 14:3

3. These were joined together They were allies and confederates . The vale of Siddim is, according to the obvious import of the words here used, the name of the ancient plain or valley in which the five kings joined together, but which, at the time of our writer, was covered by the waters of the salt sea. But these waters may cover a larger extent of surface than was included in the vale of Siddim. The word Siddim ( שׂדים ) itself means fields or plains. The sea here called the salt sea is called in Deuteronomy 4:49, “the sea of the plain;” in Esther 5:7; Esther 5:7, “the Sodomitish sea;” in Josephus, “the Asphaltic lake;” by the Arabs, Bahr Lut, “Sea of Lot;” and by the Greek writers and most moderns, “the Dead Sea . ”
