The source of the waters of Nephtoah was a landmark between Judah and Benjamin (Joshua 15:8-9; Joshua 18:15). N.W. of Jerusalem, in a line with the Hinnom valley and Kirjath Jearim, S.W. of Benjamin. Now probably Ain Lifta, two miles and a half from the city, and six from Kuriet el Enab (formerly Kirjath Jearim, but others say Emmaus and place Kirjath Jearim on the mount on the N. of which now Chesla is found; and identify Ain Karim with N.E. of wady Haninah; see Imperial Bible Dictionary).
