20 Saul and all the people who were with him were gathered together, and came to the battle; and behold, they were all striking each other with their swords in very great confusion.
21 Now the Hebrews who were with the Philistines before and who went up with them into the camp from all around, even they also turned to be with the Israelites who were with Saul and Jonathan.
22 Likewise all the men of Israel who had hidden themselves in the hill country of Ephraim, when they heard that the Philistines fled, even they also followed hard after them in the battle.
