International Standard Bible Encyclopedia
RAMATH-LEHIra'-math-le'-hi (ramath lechi, "the hill" or "height of Lehi"; Anairesis siagonos): So the place is said to have been called where Samson threw away the jaw-bone of an ass, with which he had slain 1,000 Philistines (Judges 15:17). The Septuagint seems to have supposed that the name referred to the "heaving" or throwing up of the jaw-bone. The Hebrew, however, corresponds to the form used in other placenames, such as Ramath-mizpeh, and must be read as "Ramah of Lehi." The name Lehi may have been given because of some real or imagined likeness in the place to the shape of a jaw-bone (Judges 15:9, 14, 19). It may have been in Wady es-Sarar, not far from Zorah and Timnath; but the available data do not permit of certain identification.
See JAWBONE; LEHI.

Elevation of Lehi, or the jawbone height; i.e., the Ramah of Lehi (
Judges 15:15-17). The phrase "in the jaw," ver. 19, Authorized Version, is in the margin, also in the Revised Version, "in Lehi." Here Samson slew a thousand Philistines with a jawbone.
