Jeremiah 1:18 Meaning

16And I will utter my judgments against them touching all their wickedness, who have forsaken me, and have burned incense unto other gods, and worshipped the works of their own hands.

17Thou therefore gird up thy loins, and arise, and speak unto them all that I command thee: be not dismayed at their faces, lest I confound thee before them.

18For, behold, I have made thee this day a defenced city, and an iron pillar, and brasen walls against the whole land, against the kings of Judah, against the princes thereof, against the priests thereof, 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.
