Jeremiah 1:18
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.
Galatians 2:9
And recognizing the grace that I had been given, James, Cephas, and John—those reputed to be pillars—gave me and Barnabas the right hand of fellowship, so that we should go to the Gentiles, and they to the circumcised.
