1 Samuel 14:4

Between the passages. I.e. the passes. A sharp rock. Literally, "a tooth of rock." Conder ('Tent Work,' 2:112) says, "The site of the Philistine camp at Michmash, which Jonathan and his armour bearer attacked, is very minutely described by Josephus. It was, he says, a precipice with three tops, ending in a long, sharp tongue, and protected by surrounding cliffs. Exactly such a natural fortress exists immediately east of the village of Michmash, and is still called 'the fort' by the peasantry. It is a ridge rising in three rounded knolls above a perpendicular crag, ending in a narrow tongue to the east, with cliffs below, and having an open valley behind it, and a saddle towards the west, on which Michmash itself is situate. Opposite this fortress, on the south, there is a crag of equal height, and seemingly impassable. Thus the description of the Old Testament is fully borne out—'a sharp rock on one side, and a sharp rock on the other.' The southern cliff was called Seneh , or 'the acacia,' and the same name still applies to the modern valley, due to the acacia trees which dot its course. The northern cliff was called Bozez , or 'shining,' and the true explanation of the name only presents itself on the spot." Conder then describes how, "treading perhaps almost in the steps of Jonathan, after arriving on the brink of the chasm, or defile of Michmash, they were able to descend Seneh, even with horses and mules. "I noticed," he says, "that the dip of the strata down eastward gave hopes that by one of the long ledges we might be able to slide, as it were, towards the bottom. It is not likely that horses had ever before been led along this ledge, or will perhaps ever again cross the pathless chasm, but it was just possible, and by jumping them down one or two steps some three feet high, we succeeded in making the passage.… Though we got down Seneh, we did not attempt to climb up Bozez .... Horses could scarcely find a footing anywhere on the sides of the northern precipice; but judging from the descent, it seems possible that Jonathan, with immense labour, could have 'climbed up upon his hands and upon his feet, and his armour bearer after him' ( 1 Samuel 14:13 ). That a man exhausted by such an effort could have fought successfully on arriving at the top can only be accounted for on the supposition of a sudden panic among the Philistines, when they found the enemy actually within their apparently impregnable fortress."
