Nephtoah - (Easton's Bible Dictionary)
Opened, a fountain and a stream issuing from it on the border between Judah and Benjamin (Josh. 15:8, 9; 18:15). It has been identified with Ain Lifta, a spring about 2 1/2 miles north-west of Jerusalem. Others, however, have identified it with Ain' Atan, on the south-west of Bethlehem, whence water is conveyed through "Pilate's aqueduct" to the Haram area at Jerusalem.
