1. The boundary of Solomon’s dominions on the Euphrates (1 Kings 4:24). This is doubtless the city known to the Greeks and Romans as Thapsacus, situated at the ford of the Euphrates, which well agrees with the signification of Tiphsah, “passing over.” It was where Cyrus, Darius Codomannus, and Alexander crossed during their wars. The town was a place of importance. Identified with Suriyeh, 35° 54' N, 38° 48' E. A traveler in the winter of 1841-2 found but twenty inches of water in the Euphrates at this spot.
2. City smitten by Menahem (2 Kings 15:16). This was doubtless a different place from the above, and has been identified by some with ruins at Tafsah, 32° 10' N, 35° 10' E.
