Contradiction with Acts 7:23
States that Moses was forty years old when he fled Egypt; it doesn't directly contradict Exodus 7:7, but contributes to the confusion about Moses and Aaron's ages.
Acts 7:23: And when he was full forty years old, it came into his heart to visit his brethren the children of Israel.
Contradiction with Exodus 2:11-15
Describes Moses as an adult leaving Egypt; depending on interpretation, might appear inconsistent with other chronological accounts.
Exodus 2:11-15: And it came to pass in those days, when Moses was grown, that he went out unto his brethren, and looked on their burdens: and he spied an Egyptian smiting an Hebrew, one of his brethren.
Contradiction with Numbers 33:38-39
Mentions Aaron's age at death, useful for age-related discrepancies, but not a direct contradiction with Exodus 7:7.
Numbers 33:38-39: And Aaron the priest went up into mount Hor at the commandment of the LORD, and died there, in the fortieth year after the children of Israel were come out of the land of Egypt, in the first [day] of the fifth month.
Contradiction with Exodus 4:20
Shows an active adult Moses, potentially raising questions about timeline consistency without direct contradiction to Exodus 7:7.
Exodus 4:20: And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand.
