1 Samuel 14:19-22

19And it came to pass while Saul talked to the priest, that the noise which was in the camp of the Philistines went on and increased; and Saul said to the priest, Withdraw thy hand.

20And Saul and all the people that were with him were called together, and they came to the battle; and behold, every man's sword was against his fellow, a very great confusion.

21And there were Hebrews with the Philistines before that time, who had gone up with them into the camp round about; and they also [turned] to be with the Israelites who were with Saul and Jonathan.

22And all the men of Israel who had hid themselves in mount Ephraim heard that the Philistines fled, and they also followed hard after them in the battle.
