What does 1 Samuel 15:9 mean?
The Lord commanded Saul to completely annihilate every living thing, human and animal, of the Amalekites (1 Samuel 15:3). Those lives were marked for death by God to satisfy His declaration of judgment on Amalek about four hundred years earlier (Deuteronomy 25:17–19).Saul's refusal to kill the king and permitting the Israelites to take possession of the best animals as plunder were both direct violations of the Lord's revealed will through Samuel. Saul will later offer excuses, but no reasoning will be good enough to justify doing the opposite of God's command. Partial obedience is still disobedience, and the Lord doesn't want us to think we can "do better" than what He's told us (1 Samuel 15:22–23).
