1 Samuel 14:36 - Ellicott's Commentary On The Whole Bible

Let us go down after the Philistines by night. — In the depth of the night, when the rough feasting on the captured beasts was over, King Saul would have had the bloody work begun afresh, and would have hurried after the flying Philistines, and with a wild butchery have completed the great and signal victory. With the implicit obedience which his soldiers seem ever to have shown him — whether a vow of total abstinence, or a desperate charge, or a wild night attack, or a ruthless bloodshed, was enjoined on them by their stern and gloomy king — the army professed themselves at once ready again to fight. Only one man in that army flushed with victory dared, with the bravery which alone proceeds from righteousness, to withstand the imperious sovereign. The high priest, Ahiah, doubted whether such a wholesale bloodshed as would surely have resulted from the conquering troops of Saul pursuing a dispersed and vanquished enemy, was in accordance with the will of God. No command to exterminate these Philistines had ever been given, and that day, so glorious in the annals of Israel, was wholly due to the special interposition of the Eternal Friend of Israel. Ahiah said, “Let us first inquire of the oracles of God” — alluding, of course, to the jewels of Urim and Thummim on his high-priestly ephod.
