1 Samuel 14:19-23

And it came to pass, while Saul talked unto the priest, that the noise that was in the host of the Philistines went on and increased: and Saul said unto the priest, Withdraw thine hand.

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.
