Jeremiah 1:18 YLT

¹⁶  And I have spoken My judgments with them concerning all their evil, in that they have forsaken Me, and make perfume to other gods, and bow themselves to the works of their own hands.

¹⁷  'And thou, thou dost gird up thy loins, and hast arisen, and spoken unto them all that I command thee: be not affrighted because of them, lest I affright thee before them.

¹⁸  And I, lo, I have given thee this day for a fenced city, and for an iron pillar, and for brazen walls over all the land, to the kings of Judah, to its heads, to its priests, and to the people of the land;

¹⁹  and they have fought against thee, and they prevail not against thee; for with thee 'am' I, -- an affirmation of Jehovah -- to deliver thee.
