Exodus 4:10: 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. [eloquent: Heb. a man of words] [heretofore: Heb. since yesterday, nor since the third day]
Contradiction with Exodus 3:11

Contradiction with Exodus 6:12
Presents Moses as doubtful and lacking in faith, which contradicts the careful and watchful behavior of his sister in Exodus 2:4.
Exodus 6:12: And Moses spake before the LORD, saying, Behold, the children of Israel have not hearkened unto me; how then shall Pharaoh hear me, who [am] of uncircumcised lips?
