Saul manifested a different spirit in the next campaign, the war with the Amalekites, whom, at the bidding of God, he was to exterminate. When the message of God's displeasure was conveyed to Saul by the prophet Samuel, he said: "If the Torah ordains that a heifer of the herd shall be beheaded in the valley as an atonement for the death of a single man, how great must be the atonement required for the slaughter of so many men?
And granted they are sinners, what wrong have their cattle done to deserve annihilation? And granted that the adults are worthy of their fate, what have the children done?" Then a voice proclaimed from heaven, "Be not overjust." Later on, when Saul commissioned Doeg to cut down the priests at Nob, the same voice was heard to say, "Be not overwicked."
It was this very Doeg, destined to play so baleful a part in his life, who induced Saul to spare Agag, the king of Amalekites. His argument was the law prohibits the slaying of an animal and its young on the same day. How much less permissible is it to destroy at one time old and young, men and children. As Saul had undertaken the war of extermination against Amalek only because forced into it, he was easily persuaded to let the people keep a part of the cattle alive.
As far as he himself was concerned, he could have had no personal interest in the booty, for he was so affluent that he took a census of the army by giving a sheep to every one of his soldiers, distributing not less than two hundred thousand sheep.
