The waters of Merom - Where these waters were, interpreters are not agreed. Whether they were the waters of the Lake Semechon, or the waters of Megiddo, mentioned Judges 5:19, cannot be easily determined. The latter is the more probable opinion.
Waters of Merom - i. e. “the upper waters,” the modern Bahr el Huleh, the lake Semechonitis, or Samochonitis of Josephus. This lake occupies the southern half of the Ard el Huleh, a depressed basin some 15 miles long and 3 or 4 miles wide lying between the hills of Galilee on the west and the lower spurs of Hermon on the east. The size of the lake varies with the season, and the northern side of it ends in a large swamp. The shape of the lake is triangular, the point being at the south, where the Jordan, which enters it on the north, again quits it. There is a considerable space of tableland along the southwestern shore, and here probably the troops of Jabin and his confederates were encamped, preparing to move southward when Joshua and his army fell suddenly upon them.
