1 Samuel 14:22 (KJV)

And Saul and all the people that were with him assembled themselves, and they came to the battle: and, behold, every man’s sword was against his fellow, and there was a very great discomfiture.

Moreover the Hebrews that were with the Philistines before that time, which went up with them into the camp from the country round about, even they also turned to be with the Israelites that were with Saul and Jonathan.

Likewise all the men of Israel which had hid themselves in mount Ephraim, when they heard that the Philistines fled, even they also followed hard after them in the battle.

So the Lord saved Israel that day: and the battle passed over unto Beth–aven.

And the men of Israel were distressed that day: for Saul had adjured the people, saying, Cursed be the man that eateth any food until evening, that I may be avenged on mine enemies. So none of the people tasted any food.
