Charles Spurgeon Commentary Micah 7:11-12

"A day for building thy walls! in that day shall the decree be far removed. In that day shall they come unto thee from Assyria and the cities of Egypt, and from Egypt even to the River, and from sea to sea, and [from] mountain to mountain." — Micah 7:11-12 (ASV)

This is what was to befall those who had sinned against God and oppressed his people; he would let loose the oppressors on them, and they would find enemies on every side.
