John Gill's Bible Commentary Ver. 7. And Saul smote the Amalekites , etc.] Engaging in battle with them, he overcame them, and beat them, and slew great numbers of them: from Havilah until thou comest to Shur, that is over against Egypt ; having routed them in the valley, or in whatsoever place the battle was fought, he pursued them from one end of their country to the other; from Havilah, which lay to the northeast, to Shur, which lay to the southwest, and destroyed all that came in his way between those two points, (see Genesis 25:18).
Matthew Henry Commentary
Verses 1-9 - The sentence of condemnation against the Amalekites had gone forth lon before, Ex 17:14; De 25:19, but they had been spared till they fille up the measure of their sins. We are sure that the righteous Lord doe no injustice to any. The remembering the kindness of the ancestors of the Kenites, in favour to them, at the time God was punishing the injuries done by the ancestors of the Amalekites, tended to clear the righteousness of God in this dispensation. It is dangerous to be foun in the company of God's enemies, and it is our duty and interest to come out from among them, lest we share in their sins and plagues, R 18:4. As the commandment had been express, and a test of Saul' obedience, his conduct evidently was the effect of a proud, rebelliou spirit. He destroyed only the refuse, that was good for little. Tha which was now destroyed was sacrificed to the justice of God.
