Boyd’s Bible Dictionary:
(fount of the caller). Samson’s fountain (Judg. 15:19).
Concise Bible Dictionary:
This name, signifying “the caller's spring,” was given by Samson to the place where God gave him water in answer to his call. The spring was doubtless in the rock, not in the jawbone (see margin), because of the words following, “which is in Lehi unto this day” (Judg. 15:19).
