1 Samuel 14:23 - Ellicott's Commentary On The Whole Bible

So the Lord saved Israel... — The identical words used at the Red Sea, after the deliverance of the people from Egypt. So the battle rolled westward through Beth-aven, past city and village, over Mount Ephraim. It was a decisive victory, crushing in its results to the Philistines, who were driven back so effectually as not to re-appear till the close of Saul’s reign. The king was now at liberty to develop the military character of the people; and till the disaster which closed his life and reign, his various campaigns against the idolatrous nations who surrounded Israel generally appear to have gone on from victory to victory.
