9 So Saul took charge: "Bring me the burnt offering and the peace offerings!" He went ahead and sacrificed the burnt offering. 10 No sooner had he done it than Samuel showed up! Saul greeted him. 11 Samuel said, "What on earth are you doing?" 12 I said, 'The Philistines are about to come down on me in Gilgal, and I haven't yet come before God asking for his help.' So I took things into my own hands, and sacrificed the burnt offering." 13 "That was a fool thing to do," Samuel said to Saul. "If you had kept the appointment that your God commanded, by now God would have set a firm and lasting foundation under your kingly rule over Israel. 14 As it is, your kingly rule is already falling to pieces. God is out looking for your replacement right now. This time he'll do the choosing. When he finds him, he'll appoint him leader of his people. And all because you didn't keep your appointment with God!"
15 At that, Samuel got up and left Gilgal. What army there was left followed Saul into battle. They went into the hills from Gilgal toward Gibeah in Benjamin. Saul looked over and assessed the soldiers still with him - a mere six hundred! 16 Saul, his son Jonathan, and the soldiers who had remained made camp at Geba (Gibeah) of Benjamin. The Philistines were camped at Micmash.

(Read 1 Samuel 13:8-14)
Saul broke the order expressly given by Samuel, see 1 Samuel 10:8, as to what should be done in cases of extremity. Saul offered sacrifice without Samuel, and did it himself, though he was neither priest nor prophet. When charged with disobedience, he justified himself in what he had done, and gave no sign of repentance for it. He would have this act of disobedience pass for an instance of his prudence, and as a proof of his piety. Men destitute of inward piety, often lay great stress on the outward performances of religion. Samuel charges Saul with being an enemy to himself. Those that disobey the commandments of God, do foolishly for themselves. Sin is folly, and the greatest sinners are the greatest fools. Our disposition to obey or disobey God, will often be proved by our behaviour in things which appear small. Men see nothing but Saul's outward act, which seems small; but God saw that he did this with unbelief and distrust of his providence, with contempt of his authority and justice, and with rebellion against the light of his own conscience. Blessed Saviour, may we never, like Saul, bring our poor offerings, or fancied peace-offerings, without looking to thy precious, thy all-sufficient sacrifice! Thou only, O Lord, canst make, or hast made, our peace in the blood of the cross.
Commentary on 1 Samuel 13:15-23
(Read 1 Samuel 13:15-23)
See how politic the Philistines were when they had power; they not only prevented the people of Israel from making weapons of war, but obliged them to depend upon their enemies, even for instruments of husbandry. How impolitic Saul was, who did not, in the beginning of his reign, set himself to redress this. Want of true sense always accompanies want of grace. Sins which appear to us very little, have dangerous consequences. Miserable is a guilty, defenceless nation; much more those who are destitute of the whole armour of God.
