'Fortress' in the Bible

The fortress also shall cease from Ephraim, and the kingdom from Damascus, and the remnant of Syria: they shall be as the glory of the children of Israel, saith Jehovah of hosts.

Howl, ships of Tarshish! for your fortress is laid waste.

For thou hast been a fortress to the poor, a fortress for the needy in his distress, a refuge from the storm, a shadow from the heat: for the blast of the terrible ones has been as the storm against a wall.

And the fortress of the high defences of thy walls will he bring down, lay low, bring to the ground, into the dust.
