'City of God' in the Bible

There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the most High.

Glorious things are spoken of thee, O city of God. Selah.

“I will mention Rahab (Egypt) and Babylon among those who know Me—Behold, Philistia and Tyre with Ethiopia (Cush)—‘This one was born there.’”
