1. The classical Thapsacus, the chief crossing-place on the middle Euphrates for caravans and armies, after the decline of Carchemish in the Persian period. It lay on the eastward bend of the river where it leaves its southerly course. It is named as the north-east limit of the dominions of Solomon (1Ki 4:24). 2. Tiphsah should be corrected to Tappuah, with the Lucian Septuagint, in 2Ki 15:18.
