From one end of the Bible to another, the Holy Spirit quite frequently assigns layers of spiritual significance to real personages, cities and nations.
In Ezekiel, for example, the “prince of Tyre” is an analog for Satan himself. Manifestly, the real, human prince of Tyre never appeared in Eden. Likewise, John calls Jerusalem “Sodom and Egypt” in the book of Revelation, perhaps because the people of that city have at times displayed the moral character of both places. Again, in Galatians, Paul uses Hagar and Sarah as allegories for two covenants.
Observing this principle may help us with a few verses in Micah 5 when our attempts to interpret him literally hit the wall. Back to that thought in a bit. Let’s do the comparatively easy stuff first.
