1 Samuel 15:3

3. Man and woman, infant and suckling Who dares question the right of God to inflict such judgments upon a wicked and idolatrous nation? Jehovah is governor among the nations, and in order to chastise and destroy a wicked people he may with equal justice use the wasting pestilence or the armies of Israel. See note on Joshua 6:21.

Ox and sheep, camel and ass Such utter destruction of all the spoil would show that the Israelites fought not to enrich themselves with the possessions of their enemies, but simply as the ministers of God’s wrath to execute his judgments. Saul’s sparing of the best of the spoils was, therefore, a rash and offensive meddling with the Divine judgments. Like Achan’s offence, it was appropriating a part of the accursed thing to private use.
