He now begins to enlarge on their outward prosperity, viz., that the people of Israel shall be powerful and flourishing, and endowed with a warlike spirit to resist the assaults of their enemies; for it would not be sufficient that they should abound with all blessings, unless the ability to defend them should also be superadded. It is by no means a probable conjecture that he speaks of Saul who made prisoner of their king, Agag, in the battle with the Amalekites; but their opinion is the more correct one, who suppose that this was a name common to all the kings of that nation. It was, therefore, God’s intention to declare the superiority of His chosen people to the Amalekites; nor need we be surprised that they should be thus brought into especial antagonism with them, not only because they were the constant enemies of Israel, but because their power was then excessively great, as we shall very soon see: “Amalek was the first of nations,” etc. (verse 20.)
