Exodus 4:13

¹¹And the Lord said to Moses, Who has given a mouth to man, and who has made the very hard of hearing, and the deaf, the seeing and the blind? have not I, God?

¹²And now go and I will open thy mouth, and will instruct thee in what thou shalt say.

— Exodus 4:13 —

¹⁴And the Lord was greatly angered against Moses, and said, Lo! is not Aaron the Levite thy brother? I know that he will surely speak to thee; and, behold, he will come forth to meet thee, and beholding thee he will rejoice within himself.

¹⁵And thou shalt speak to him; and thou shalt put my words into his mouth, and I will open thy mouth and his mouth, and I will instruct you in what ye shall do.
