'Fortress' in the Bible

The fortress shall cease from Ephraim, and the kingdom from Damascus, and the remnant of Syria. They will be as the glory of the children of Israel," says Yahweh of Armies.

He has brought the high fortress of your walls down, laid low, and brought to the ground, even to the dust.

he will dwell on high. His place of defense will be the fortress of rocks. His bread will be supplied. His waters will be sure.
