9 So Saul said, "Bring a burnt offering and peace offerings here to me." And he offered the burnt offering. 10 Now it happened, as soon as he had finished presenting the burnt offering, that Samuel came; and Saul went out to meet him, that he might greet him. 11 And Samuel said, "What have you done?" And Saul said, "When I saw that the people were scattered from me, and that you did not come within the days appointed, and that the Philistines gathered together at Michmash, 12 then I said, 'The Philistines will now come down on me at Gilgal, and I have not made supplication to the Lord.' Therefore I felt compelled, and offered a burnt offering." 13 And Samuel said to Saul, "You have done foolishly. You have not kept the commandment of the Lord your God, which He commanded you. For now the Lord would have established your kingdom over Israel forever. 14 But now your kingdom shall not continue. The Lord has sought for Himself a man after His own heart, and the Lord has commanded him to be commander over His people, because you have not kept what the Lord commanded you."
15 Then Samuel arose and went up from Gilgal to Gibeah of Benjamin. And Saul numbered the people present with him, about six hundred men. 16 Saul, Jonathan his son, and the people present with them remained in Gibeah of Benjamin. But the Philistines encamped in Michmash.

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.

(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.
