'Fortified' in the Bible

You shall point out a way for the [Babylonian] sword to come to Rabbah [the capital] of the sons of Ammon, and to Judah into fortified Jerusalem.

He will kill your daughters on the mainland with the sword, and he shall make siege walls against you and build a siege ramp against you and raise [a roof of] large shields [as a defense] against you.

Then they will say, ‘This land that was deserted and desolate has become like the garden of Eden; and the waste, desolate, and ruined cities are fortified and inhabited.’
