Between the passes, by which Jonathan sought to go over to 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.
Half a furrow of land (1 Samuel 14:14) was half a parcel of land that a yolk of oxen could plow in one day. Evidently God assisted Jonathan by sending a mild earthquake to unnerve the Philistines further (1 Samuel 14:15; cf. Deuteronomy 7:23).
