John Gill's Bible Commentary Ver. 7. The Lord shall cause thine enemies that rise up against thee to be smitten before thy face , etc.] As the Philistines, Moabites, Syrians, Edomites, and Ammonites were, especially in the times of David: they shall come out against thee one way : in a body, all together, in large numbers, marching in great order, to give them battle: and flee before thee seven ways ; be entirely routed, and flee some one way, and some another, even every way they could take to make their escape.
The phrase is expressive of an entire victory, and of a complete rout and dispersion of an enemy.
Matthew Henry Commentary
Verses 1-14 - This chapter is a very large exposition of two words, the blessing an the curse. They are real things and have real effects. The blessing are here put before the curses. God is slow to anger, but swift to sho mercy. It is his delight to bless. It is better that we should be draw to what is good by a child-like hope of God's favour, than that we be frightened to it by a slavish fear of his wrath. The blessing i promised, upon condition that they diligently hearken to the voice of God. Let them keep up religion, the form and power of it, in their families and nation, then the providence of God would prosper all their outward concerns.
