What position and power did Moses have in Egypt according to Acts?

Les explains that Acts chapter 7 supplies details omitted from Genesis. Moses was born in the time when the pharaohs no longer remembered Joseph. He was exceeding fair—not merely a pretty baby, but a special child in God's line of service—and his parents, by faith, understood God would use him and took special steps to save his life. Pharaoh's daughter took him up and nourished him as her own son. Being raised in the king's palace, Moses was educated in all the wisdom of the Egyptians. Scripture gives the added detail that Moses was the top man in Egypt under Pharaoh, highly educated, with a lot of power, and mighty in word and deeds. Les also notes Moses' life broke into segments of 40 years: 40 years in Pharaoh's palace, 40 years on the back side of the desert herding sheep, and then 40 years leading the children of Israel.
