Proverbs 18:19
An offended brother is harder to win than a fortified city, and disputes are like the bars of a castle.
Jeremiah 1:18, 19
Now behold, this day I have made you like a fortified city, an iron pillar, and bronze walls against the whole land—against the kings of Judah, its officials, its priests, and the people of the land. / They will fight against you but will never overcome you, since I am with you to deliver you,” declares the LORD.
