Jeremiah 1:4-8

Now the word of the Lord came to me saying, ‘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.’ Then I said, ‘Ah, Lord God! Truly I do not know how to speak, for I am only a boy.’ But the Lord said to me, ‘Do not say, “I am only a boy”; for you shall go to all to whom I send you, and you shall speak whatever I command you. Do not be afraid of them, for I am with you to deliver you,
says the Lord.’
