Jeremiah 1:17-19

17Thou therefore gird up thy loins, and arise, and speak to them all that I command thee: be not dismayed at their faces, lest I confound thee before them.1 18For, behold, I have made thee this day a fortified city, and an iron pillar, and brasen walls against the whole land, against the kings of Judah, against its princes, against its priests, and against the people of the land. 19And they shall fight against thee; but they shall not prevail against thee; for I am with thee, saith the LORD, to deliver thee.
