Jeremiah 1:4-8
4 The word of the Lord came to me, saying, 5 “Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations.” 6 “Alas, Sovereign Lord,” I said, “I do not know how to speak; I am too young.” 7 But the Lord said to me, “Do not say, ‘I am too young.’ You must go to everyone I send you to and say whatever I command you. 8 Do not be afraid of them, for I am with you and will rescue you,” declares the Lord.
