Then the word of the LORD came unto me, saying, Before I formed you in the womb I knew you; and before you came forth out of the womb I sanctified you, and I ordained you a prophet unto the nations. Then said I, Ah, Lord GOD! behold, I cannot speak: for I am a child. But the LORD said unto me, Say not, I am a child: for you shall go to all that I shall send you, and whatsoever I command you you shall speak. (Jeremiah 1:4-7)
