Exodus 4:10-12

10But Moses said to the Lord, “Oh, my Lord, I am not eloquent, either in the past or since you have spoken to your servant, but aI am slow of speech and of tongue.” 11Then the Lord said to him, “Who has made man’s mouth? Who makes him mute, or deaf, or seeing, or blind? Is it not I, the Lord? 12Now therefore go, and bI will be with your mouth and teach you what you shall speak.”

Jeremiah 1:6

6Then I said, “Ah, Lord God! Behold, cI do not know how to speak, dfor I am only a youth.”

Matthew 10:19-20

19 eWhen fthey deliver you over, gdo not be anxious how you are to speak or what you are to say, for hwhat you are to say will be given to you in that hour. 20 iFor it is not you who speak, but jthe Spirit of your Father speaking through you.
