Exodus Chapter 4, Verse 10
From BibleWiki
10: And Moses said unto the LORD, O my LORD, I am not eloquent,
neither heretofore, nor since thou hast spoken unto thy
servant: but I am slow of speech, and of a slow tongue.
10: And Moses said to the Lord, I pray, Lord, I have not been sufficient in former times, neither from the time that thou hast begun to speak to thy servant: I am weak in speech, and slow-tongued.
Moses raised another difficulty. "I am not a man of words," he said (i.e., I do not possess the gift of speech), "but am heavy in mouth and heavy in tongue" (i.e., I find a difficulty in the use of mouth and tongue, not exactly "stammering"); and that "both of yesterday and the day before" (i.e., from the very first, Gen 31:2), "and also since Thy speaking to Thy servant." Moses meant to say, "I neither possess the gift of speech by nature, nor have I received it since Thou hast spoken to me."
