When he came to Lehi, the Philistines shouted as they met him: and the Spirit of Yahweh came mightily on him, and the ropes that were on his arms became as flax that was burnt with fire, and his bands dropped from off his hands.
The "hollow place" that God clave was not in the jawbone, but in the place thus named, and the reference would appear to be to a miraculous provision of water to save Samson's life, much as God had done for the children of Israel in the wilderness.  This, of course, is proved by the fact that the spring in Lehi was named, "The Spring of the Caller," that is, the "Spring of Him Who Called upon God."[15]  In Hebrew, the partridge is called "The Caller"; and thus the spring eventually was called "Spring of the Partridge."  We consider that change much more likely than the notion expressed by Moore, that, "The original name was `Partridge Spring.'"[16]  There could not possibly have been any special reason for such a designation before the event recorded here.
