I.e., Thapsacus, on the western bank of the Euphrates, the river being at that point fordable; a boundary of Solomon’s dominions (1 Kgs. 4: 24); also famous in classic history as the place where Cyrus with his 10,000 Greeks crossed the river. The place of this name mentioned in 2 Kgs. 15: 16 is probably within the kingdom of Israel; its site is unknown.
