Exodus 4:10-16 And Moses said to the Lord, I pray, Lord, I have not been sufficient in former times, neither from the time that you have begun to speak to your servant: I am weak in speech, and slow-tongued.

LXX2012⁽ⁱ⁾ ¹⁰ And Moses said to the Lord, I pray, Lord, I have not been sufficient in former times, neither from the time that you have begun to speak to your servant: I am weak in speech, and slow-tongued. ¹¹ And 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? ¹² And now go and I will open your mouth, and will instruct you in what you shall say. ¹³ And Moses said, I pray you, Lord, appoint another able [person] whom you shall send. ¹⁴ And the Lord was greatly angered against Moses, and said, Behold! is not Aaron the Levite your brother? I know that he will surely speak to you; and, behold, he will come forth to meet you, and beholding you he will rejoice within himself. ¹⁵ And you shall speak to him; and you shall put my words into his mouth, and I will open your mouth and his mouth, and I will instruct you in what you⌃ shall do. ¹⁶ And he shall speak for you to the people, and he shall be your mouth, and you shall be for him in things pertaining to God.
