Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
Nevertheless Saul is put to a final proof. Jehovah, by the mouth of Samuel, sends him to smite Amalek, and utterly destroy them and all that belonged to them. They were the cruel and determined enemies of God's people (Deu 25:17-19). They had been chief among the nations, their name and their pride were everywhere known (Num 24:7; Num 24:20); but it was a nation doomed of God.
God now entrusts Saul with the fulfilment of Deu 25:19. In this case all Israel accompanied him without fear. These were not the enemies from within who were daily wearing away their strength and courage. The victory is complete. The only question now is that of faithfulness to God, and of preferring His glory to self-interest. But Saul fears the people. The Spirit of God says "Saul and the people"; Saul says "the people"; and that it was for God they spared. But our excuses, even when true, only condemn us. Saul, not having faith, not looking to God, fears the people more than God. What a slave is the unbeliever! If not the slave of the enemy, he is that of the people whom he appears to govern. Saul, unfaithful to God in the midst of the people, and surrounded by blessings from Jehovah, is at length deprived of the kingdom. No humiliation, no brokenness of heart-he confesses his sin, hoping to avoid its punishment; but, unable to escape it, he entreats Samuel to honour him in spite of it. Samuel does so and then forsakes him. Everything changes now, and David appears on the scene. It is well to remark that the connected history of Saul's reign closes with the end of chapter 14. Chapter 15 is given as a separate history on account of the importance of its contents-the definite rejection of Saul, a rejection which introduces David.
