12 and I say, Now do the Philistines come down unto me to Gilgal, and the face of Jehovah I have not appeased; and I force myself, and cause the burnt-offering to ascend.' 13 And Samuel saith unto Saul, 'Thou hast been foolish; thou hast not kept the command of Jehovah thy God, which He commanded thee, for now had Jehovah established thy kingdom over Israel unto the age; 14 and, now, thy kingdom doth not stand, Jehovah hath sought for Himself a man according to His own heart, and Jehovah chargeth him for leader over His people, for thou hast not kept that which Jehovah commanded thee.'

Commentary on 1 Samuel 13:8-14
(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.
