Albert Barnes Commentary 1 Samuel 14:4

"And between the passes, by which Jonathan sought to go over unto the Philistines` garrison, there was a rocky crag on the one side, and a rocky crag on the other side: and the name of the one was Bozez, and the name of the other Seneh." — 1 Samuel 14:4 (ASV)

The southern cliff was called “Seneh,” or “the acacia,” and this name still applies to the modern valley, which is dotted with acacias. The northern cliff was named “Bozez,” or “Shining.” The valley runs nearly due east, and the northern cliff has a ruddy and tawny tint, is crowned with gleaming white chalk, and stands in the full glare of the sun for almost the entire day.
