New King James Version
17 “Therefore (D)prepare yourself and arise,
And speak to them all that I command you.
(E)Do not be dismayed before their faces,
Lest I dismay you before them.
18 For behold, I have made you this day
(F)A fortified city and an iron pillar,
And bronze walls against the whole land—
Against the kings of Judah,
Against its princes,
Against its priests,
And against the people of the land.
