'Habitable' in the Bible

Then he led Jesus up [to a high mountain] and displayed before Him all the kingdoms of the inhabited earth [and their magnificence] in the twinkling of an eye.

And when He again brings the firstborn [highest-ranking Son] into the world, He says,“And all the angels of God are to worship Him.”

It was not to angels that God subjected the [inhabited] world of the future [when Christ reigns], about which we are speaking.
