Commentaries
15:32-35 Many think the bitterness of death is past when it is not gone by; they put that evil day far from them, which is very near. Samuel calls Agag to account for his own sins. He followed the example of his ancestors' cruelty, justly therefore is all the righteous blood shed by Amalek required. Saul seems unconcerned at the token of God's displeasure which he lay under, yet Samuel mourns day and night for him. Jerusalem was carnally secure while Christ wept over it. Do we desire to do the whole will of God? Turn to him, not in form and appearance, but with sincerity.
33. Samuel hewed Agag—This cruel tyrant met the retribution of a righteous Providence. Never has it been unusual for great or official personages in the East to perform executions with their own hands. Samuel did it "before the Lord" in Gilgal, appointing that same mode of punishment (hitherto unknown in Israel) to be used towards him, which he had formerly used towards others.
