But the Lord sent His servant with another message to Saul. By obedience he might still prove his fidelity to God and his worthiness to walk before Israel. Samuel came to the king and delivered the word of the Lord. That the monarch might realize the importance of heeding the command, Samuel expressly declared that he spoke by divine direction, by the same authority that had called Saul to the throne. The prophet said, “Thus saith the Lord of hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way, when he came up from Egypt. Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.” 1 Samuel 15:2, 3L. The Amalekites had been the first to make war upon Israel in the wilderness; and for this sin, together with their defiance of God and their debasing idolatry, the Lord, through Moses, had pronounced sentence upon them. By divine direction the history of their cruelty toward Israel had been recorded, with the command, “Thou shalt blot out the remembrance of Amalek from under heaven; thou shalt not forget it.” Deuteronomy 25:19L. For four hundred years the execution of this sentence had been deferred; but the Amalekites had not turned from their sins. The Lord knew that this wicked people would, if it were possible, blot out His people and His worship from the earth. Now the time had come for the sentence, so long delayed, to be executed.
