Saul ... spared Agag

Samuel told Saul that God wanted him to completely destroy the Amalekite people and animals. Saul fought the Amalekites and killed all the people except the king. He destroyed the animals that were not very good but saved the best animals. Saul told Samuel he had obeyed God's command. Saul said he had saved them for a sacrifice to God. God said that obedience was better than sacrifice. Because Saul had disobeyed, God had chosen someone else to become king.
