1 Samuel 13:3-4

(3) And Jonathan smote the garrison of the Philistines that was in Geba, and the Philistines heard of it. And Saul blew the trumpet throughout all the land, saying, Let the Hebrews hear. (4) And all Israel heard say that Saul had smitten a garrison of the Philistines, and that Israel also was had in abomination with the Philistines. And the people were called together after Saul to Gilgal.

Here is an act of presumption in Saul, unadvised of God, and as it should seem, treacherous to men. The Philistines throughout the land soon heard of the treachery done by the Israelites to one of their garrisons, and as is common among men, the whole nation took indignation at it. Let the Reader fail not to trace the hand of God in it. For as there is no intercourse between Saul and the Lord by prayer, there is no communion by way of counsel to direct him.
