1 Samuel 14:19-22

19And it came to pass, while Saul talked unto the priest, that the tumult that was in the camp of the Philistines went on and increased: and Saul said unto the priest, Withdraw thine hand.

20And Saul and all the people that were with him were gathered together, and came to the battle: and, behold, every man’s sword was against his fellow, and there was a very great discomfiture.

21Now the Hebrews that were with the Philistines as beforetime, 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.

22Likewise all the men of Israel which had hid themselves in the hill country of Ephraim, when they heard that the Philistines fled, even they also followed hard after them in the battle.
