“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.”
King James Version (KJV)
14:21 Which went - Either by constraint, as servants; or in policy, to gain their favour and protection.
14:23 The battle - That is, the warriors who were engaged in the battle, and were pursuing the Philistines. Yet it is said, the Lord saved Israel that day: he did it by them: for without him they could do nothing. Salvation is of the Lord.
14:24 Distressed - With hunger, and weakness, and faintness, and all by reason of the following oath. Avenged - As Saul's intention was good, so the matter of the obligation was not simply unlawful, if it had not been so rigorous in excluding all food, and in obliging the people to it under pain of an accursed death, which was a punishment far exceeding the fault.
