“Get yourself ready! Stand up and say to them whatever I command you. Do not be terrified by them, or I will terrify you before them. Today I have made you a fortified city, an iron pillar and a bronze wall to stand 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 not overcome you, for I am with you and will rescue you,” declares the Lord.

Jeremiah 1:17-19
