1 Samuel 15:1 - Joseph Benson’s Commentary on the Old and New Testaments

Hearken thou unto the voice of the Lord Thou hast erred already; now regain God's favour by thy exact obedience to what he commands. Thus saith the Lord, I remember, &c. Now I will avenge those old injuries of the Amalekites on their children, who continue in their parents' practices. God here refers to that most notorious instance of cruelty, inhumanity, and impiety, their invading and destroying, as far as in them lay, by treachery and surprise, and that uninjured and unprovoked, the people of Israel, when they were coming out of Egypt, and were manifestly under the immediate and miraculous protection of Almighty God. “This was a sin,” says Dr. Delaney, “at once so inhuman and so atheistical, as perhaps cannot be paralleled in any one instance from the foundation of the world, and therefore it is no wonder if this flagrant act of villany and impiety produced that dreadful decree against them, recorded Exodus 17:14, I will utterly put out the remembrance of Amalek from under heaven: and again, 1 Samuel 15:16, The Lord hath sworn that he will have war with Amalek, from generation to generation. To reconcile this severe decree with the principles of justice, and God's own declaration, (Ezekiel 18.,) of his limiting the vengeance of guilt to the person of the offender, we need only to reflect upon one plain observation, with which every day's experience sufficiently furnishes us, that nothing is more common than for children to be unrepentant, and, it may be, improved and inveterate in the sins of their ancestors: and that nothing is more easy to the divine prescience than to foresee this, and to pronounce upon it. And that this was the case of the Amalekites, sufficiently appears from their history. For, as their fathers attempted upon the Israelites, when under the manifest protection of God, their sons continued to do the same upon every occasion, though the same protection became every day more and more conspicuous by many and repeated instances.” When he came out of Egypt When he was newly come out of cruel and long bondage, and was now weak, and weary, and faint, and hungry, Deuteronomy 25:18; and therefore it was barbarous, instead of that pity which even nature prompted them to afford, to add affliction to the afflicted; it was also horrid impiety to fight against God himself, and to lift up their hand in a manner, against the Lord's throne, while they struck at that people which God had brought forth in so stupendous a way.
