 Ephes-dammim
    boundary of blood, a place in the tribe of Judah where the
    Philistines encamped when David fought with Goliath (1 Sam.
    17:1). It was probably so called as having been the scene of
    frequent sanguinary conflicts between Israel and the
    Philistines. It is called Pas-dammim (1 Chr. 11:13). It has been
    identified with the modern Beit Fased, i.e., "house of
    bleeding", near Shochoh (q.v.).
