Charles Ellicott Commentary 1 Samuel 14:13

"And Jonathan climbed up upon his hands and upon his feet, and his armorbearer after him: and they fell before Jonathan; and his armorbearer slew them after him." — 1 Samuel 14:13 (ASV)

And they fell before Jonathan ... — The sign he prayed for was given to him. There were probably only a few sentinels at their posts; the inaccessibility of the craggy fortress had lulled the garrison into security.

The few watching him at first mocked, and then, as Jonathan advanced with strange rapidity, they seem to have been, as it were, paralyzed—the feat was hardly human—as the man, fully armed, sprang over the rocky parapet.

“His chief weapon was his bow,” writes Dean Stanley; “his whole tribe was a tribe of archers, and he was the chief archer of them all.”

Arrived at the summit, in rapid succession he shot his deadly bolts, his gallant armour-bearer following his chief’s example, and twenty men, so says the record, fell before they had recovered from their surprise.

In a moment a panic seized the garrison, and a hurried flight ensued, for they felt they had to deal with no mortal strength.
