Tiph´sah, a large and opulent city on the western bank of the Euphrates. It is doubtless the same as the Thapsacus of the Greeks and Romans. The name means 'ford;' and the town was, in fact, situated at the lowest fording-place of the Euphrates; whence it became the point of trading-communication between the natives east and west of the river. On this account, and as commanding the ford, the possession of the place was deemed of great importance by the ruling powers of the day. This circumstance explains the contentions of the kings of Syria and Egypt respecting Carchemish, which was a strong place a little lower down the river, at the junction of the Chaboras. Solomon obtained possession of Tiphsah (), probably in connection with the series of operations (of which the building or fortification of Tadmor was one) adopted by him for the purpose of drawing the Eastern trade into his own dominions [SOLOMON; TADMOR]. Nothing remains of Tiphsah at the present-day except the name; but the site is supposed to be marked by the village of Ed-Deyr.
