Jeremiah 1: 4 - 5, 17 - 19
4 Now the word of the LORD came to me saying,
5 "Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations."
17 But you, gird up your loins; arise, and say to them everything that I command you. Do not be dismayed by them, lest I dismay you before them.
18 And I, behold, I make you this day a fortified city, an iron pillar, and bronze walls, against the whole land, against the kings of Judah, its princes, its priests, and the people of the land.
19 They will fight against you; but they shall not prevail against you, for I am with you, says the LORD, to deliver you."
