Jeremiah 1:6-8 King James Version (KJV)
6 Then said I, Ah, Lord God! behold, I cannot speak: for I am a child.
7 But the Lord said unto me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.
8 Be not afraid of their faces: for I am with thee to deliver thee, saith the Lord.
