1 Samuel 14:11
And both of them discovered themselves unto the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves. And both of them discovered themselves unto the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves.
Jonathan and his armor-bearer had withdrawn secretly from the Israelite camp at Geba and passed down into the gorge between Geba and Michmash under the shadow of the cliff and partly concealed by mounds and ridges, and the verse marks the moment when they then came into view as they approached the Philistine fortress. Jonathan was one who feared the Lord, and his armor-bearer was a man of faith and prayer. Before advancing they prayed earnestly and agreed on a sign to determine how to proceed, trusting by divine impulse that God could deliver Israel by few or by many.
The Philistines knew the Israelites were weak and hiding in holes and other secret places. So when the two men were revealed they mocked them as cowards and as Hebrews coming forth out of the holes where they had hid themselves. They challenged them to come up to be punished for their daring. God had brought matters to this crisis to rebuke Saul for his perversity in his presumptuous offering and to teach humility and faith, and He would not give Saul the honor of vanquishing the Philistines but chose Jonathan as the instrument to deliver Israel.
That Philistine challenge to come up was the agreed token that the Lord would prosper the undertaking. After receiving the token the two men passed from sight and climbed by a secret and difficult path to the top of a cliff deemed inaccessible and weakly guarded. They entered the camp and killed the surprised and fearful sentinels without resistance, so that God worked through the two men to defeat the Philistines.
