For I, behold, I have made you this day a fortified city and an iron pillar and bronze walls against the whole land–against the [successive] kings of Judah, against its princes, against its priests, and against the people of the land [giving you divine strength which no hostile power can overcome]. [Isa. 50:7; 54:17; Jer. 6:27; 15:20; Luke 21:15; Acts 6:10.]
