Clarke's Bible Commentary - 1 Samuel 14:22
Verse 22. The men-which had hid themselves] See 1 Samuel xiii. 6. The Vulgate and the Septuagint add here, And there were with Saul about ten thousand men; but this is supported by no other authority.
John Gill's Bible Commentary
Ver. 22. Likewise all the men of Israel which had hid themselves in Mount Ephraim , etc.] In the caves and rocks, thickets and pits there, (see Samuel 13:6) when they heard that the Philistines fled ; now being delivered from their fears, and thinking themselves safe, ventured out of their lurking places: even they also followed hard after them in the battle ; they joined the pursuers who came their way, and stuck to them, and closely pursued the flying army of the Philistines. According to Josephus f271 , the army of Saul was now increased to 10,000.
Matthew Henry Commentary
Verses 16-23 - The Philistines were, by the power of God, set against one another. The more evident it was that God did all, the more reason Saul had to inquire whether God would give him leave to do any thing. But he was in such haste to fight a fallen enemy, that he would not stay to end his devotions, nor hear what answer God would give him. He that believeth will not make such haste, nor reckon any business so urgent, as not to allow time to take God with him.
