Contradiction with Exodus 4:10
Exodus 4:10 shows Moses expressing doubt in his speaking ability, whereas in Exodus 33:12, he is confidently conversing with God, showing a different level of assurance and leadership.
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
In Exodus 3:11, Moses doubts his capacity to lead, whereas in Exodus 33:12, he is seen as firmly requesting guidance from God, suggesting confidence and a sense of duty.
Exodus 3:11: And Moses said unto God, Who [am] I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?
Contradiction with Numbers 12:3
Numbers 12:3 describes Moses as the meekest man on earth, which seems contradictory to his assertive and bold dialogue with God in Exodus 33:12.
Numbers 12:3: (Now the man Moses [was] very meek, above all the men which [were] upon the face of the earth.)
Contradiction with Exodus 6:12
Exodus 6:12 again depicts Moses doubting his ability to lead due to his 'uncircumcised lips,' in contrast to the authoritative conversation he has with God in Exodus 33:12.
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?
