Note 5 at Acts 7:22: The Egyptians were the most advanced civilization in the world during the time of Moses. For Moses to be, "learned in all the wisdom of the Egyptians" meant that he was certainly no "dummy," as he claimed to be when trying to dodge God's call (Ex. 4:10). Josephus, who wrote a history of the Jewish people in the first century, said that Moses was general of the Egyptian army and defeated the invading Ethiopian army.

Note 6 at Acts 7:22: This is in sharp contrast with what Moses said in Exodus 4:10. It must be that Stephen, under the inspiration of the Holy Spirit, spoke the truth and that Moses simply lied to God in an attempt to excuse himself from service.
