Jeremiah 1:16-18

16 And I will utter my judgments against them concerning all their wickedness, in that they have forsaken me, and have burned incense to other gods, and worshipped the works of their own hands.

17 Thou therefore gird up thy loins, and arise, and speak to them all that I command thee. Be not dismayed at them, lest I dismay thee before them.

18 For, behold, I have made thee this day a fortified city, and an iron pillar, and brazen walls, against the whole land, against the kings of Judah, against the rulers of it, against the priests of it, and against the people of the land.
