1 Samuel 17:11 - Ellicott's Commentary On The Whole Bible

They were dismayed, and greatly afraid. — Saul the king, perhaps, was restrained from personally accepting the challenge by motives of dignity, but the marked silence on his part, and the utter hopelessness of his army, reads in strange contrast to the former records of Hebrew daring. Where was Jonathan, for instance, ever the bravest of the brave, and his gallant armour-bearer? There had assuredly been a time when neither motives of dignity nor prudence would have restrained Saul and his warriors from accepting the challenge of the uncircumcised enemy. We notice, too, here there is no inquiry of the Urim and Thummim, no mention of prayer to the God of the armies of Israel. An evil spirit was indeed upon the King of Israel.
