“Tiphsah” means ford

Tiphsah: is mentioned in (1 Kings 4:24) as the limit of Solomon's empire toward the Euphrates and in (2 Kings 15:16) it is said to have been attacked by Menahemi. It was known to the Greeks and Romans under the name of Thapsacus, and was the point where it was usual to cross the Euphrates. Thapsacus has been generally placed at the modern Deir ; but the Euphrates expedition proved that there is no ford at Deir , and that the only ford in this part of the course of the Euphrates is at Suriyeh , 45 miles below Balis, and 165 above Deir . This, then, must have been the position of Thapsacus.
