It came to pass, when David had made an end of speaking these words to Saul, that Saul said, Is this your voice, my son David? Saul lifted up his voice, and wept.
"David and his men went up to the stronghold"  (1 Samuel 24:22).  Engedi was 700 feet below sea level; and that stronghold to which David and his men went up to seems to have been at some higher elevation in the highlands of southern Judah.  Some scholars suggest that it might have been the cave of Adullam, but Willis rejected that idea and wrote that, "The writer had in mind the stronghold of Engedi."[17] This seems to be correct, in which case, "went up to" would mean that the conversation with Saul had taken place at some lower level than that of the stronghold.  Many questions of this nature are unanswerable without more information than is provided in the sacred text.
