Saul and all Israel - were dismayed - They saw no man able to accept the challenge.

When Saul and all Israel heard these words of the Philistine,.... For they were delivered with such a tone and strength of voice, as to be heard very generally, at least by many, and which soon was reported through the whole army:

they were dismayed, and greatly afraid; which may seem strange, when there were so many valiant men among them, as Saul himself, who had behaved with so much courage against the Ammonites, Philistines, and Amalekites; but now the Spirit of God was departed from him, and he was become timorous and fearful; and though he was much better than he had been, yet still he was not the man of spirit and resolution as before: there was also Abner, the general of his army, a very valiant man, a great man in Israel, and yet appears not on this occasion; and, what is more wonderful, Jonathan the son of Saul was present, as appears from 1 Samuel 18:1 who had not only smitten a garrison of the Philistines, but with one man more only had attacked another garrison, and routed the whole army of the Philistines, and yet now shows not his head against a single man: so it is when God cuts off the spirits of princes, or takes away their courage; victory over this man, and the glory of it, were reserved for David; and all this fear and dread throughout the armies of Israel were suffered, that he might appear the more glorious.

At these words Saul and all Israel were dismayed and greatly afraid, because not one of them dared to accept the challenge to fight with such a giant.

When Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid.

17:11 Afraid - This may seem strange, considering the glorious promises, and their late experience of divine assistance. And where was Jonathan, who in the last war had so bravely engaged an whole army of the Philistines? Doubtless he did not feel himself so stirred up of God as he did at that time. As the best, so the bravest of men, are no more than what God makes them. Jonathan must sit still now, because this honour is reserved for David.

17:1-11 Men so entirely depend upon God in all things, that when he withdraws his help, the most valiant and resolute cannot find their hearts or hands, as daily experience shows.
