Jeremiah 1:6-8

6 Then I said, “Ah, Lord God! Truly, I cannot speak, for I am a youth.”

7 But the Lord said to me, “Do not say, ‘I am a youth.’ For you shall go everywhere that I send you, and whatever I command you, you shall speak.

8 Do not be afraid of their faces. For I am with you to deliver you,” says the Lord.
