Charles Ellicott Commentary Deuteronomy 28:7

"Jehovah will cause thine enemies that rise up against thee to be smitten before thee: they shall come out against thee one way, and shall flee before thee seven ways." — Deuteronomy 28:7 (ASV)

And flee before you seven ways. — “So is the custom of those who are terrified, to flee, scattering in every direction” (Rashi). See the story of the flight of the Midianites (Judges 7:21–22), and of the Syrians (2 Kings 7:7).
