1 Samuel 14:20-24

Then Saul and all the people who were with him rallied and came to the battle; and behold, every man’s sword was against his fellow Philistine, and there was very great confusion.

Now the Hebrews who were with the Philistines previously, who went up with them all around in the camp, even they also returned to be with the Israelites who were with Saul and Jonathan.

When all the men of Israel who had kept themselves hidden in the hill country of Ephraim heard that the Philistines had fled, they also closely pursued them in the battle.

So the Lord saved Israel that day, and the battle spread beyond Beth-aven. Saul’s Foolish Order

Now the men of Israel were hard-pressed on that day, for Saul had put the people under oath, saying, “Cursed be the man who eats food before evening, and before I have avenged myself on my enemies.” So none of the people tasted food.
