The forbearance that God has exercised toward the wicked, emboldens men in transgression; but their punishment will be none the less certain and terrible for being long delayed. “The Lord shall rise up as in Mount Perazim, He shall be wroth as in the valley of Gibeon, that He may do His work, His strange work; and bring to pass His act, His strange act.” Isaiah 28:21. To our merciful God the act of punishment is a strange act. “As I live, saith the Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live.” Ezekiel 33:11. The Lord is “merciful and gracious, long-suffering, and abundant in goodness and truth, ... forgiving iniquity and transgression and sin.” Yet He will “by no means clear the guilty.” Exodus 34:6, 7. While He does not delight in vengeance, He will execute judgment upon the transgressors of His law. He is forced to do this, to preserve the inhabitants of the earth from utter depravity and ruin. In order to save some He must cut off those who have become hardened in sin. “The Lord is slow to anger, and great in power, and will not at all acquit the wicked.” Nahum 1:3. By terrible things in righteousness He will vindicate the authority of His downtrodden law. And the very fact of His reluctance to execute justice testifies to the enormity of the sins that call forth His judgments and to the severity of the retribution awaiting the transgressor.

But while inflicting judgment, God remembered mercy. The Amalekites were to be destroyed, but the Kenites, who dwelt among them, were spared. This people, though not wholly free from idolatry, were worshipers of God and were friendly to Israel. Of this tribe was the brother-in-law of Moses, Hobab, who had accompanied the Israelites in their travels through the wilderness, and by his knowledge of the country had rendered them valuable assistance.

Since the defeat of the Philistines at Michmash, Saul had made war against Moab, Ammon, and Edom, and against the Amalekites and the Philistines; and wherever he turned his arms, he gained fresh victories. On receiving the commission against the Amalekites, he at once proclaimed war. To his own authority was added that of the prophet, and at the call to battle the men of Israel flocked to his standard. The expedition was not to be entered upon for the purpose of self-aggrandizement; the Israelites were not to receive either the honor of the conquest or the spoils of their enemies. They were to engage in the war solely as an act of obedience to God, for the purpose of executing His judgment upon the Amalekites. God intended that all nations should behold the doom of that people that had defied His sovereignty, and should mark that they were destroyed by the very people whom they had despised.
