Why was Moses educated in all the wisdom of the Egyptians?
Moses was educated in all the wisdom of the Egyptians because Pharaoh's daughter took him up and nourished him as her own son, so he was raised in the king's palace. Scripture shows he became the top man in Egypt under Pharaoh, highly educated, mighty in word and deeds.
Les explains that Acts chapter 7 provides details left out of Genesis. Moses was exceeding fair, a special child in God's line of service, and his parents understood by faith that God would use him, so they took special steps to save his life. When he was cast out onto the river, Pharaoh's daughter took him up and nourished him for her own son. That is why he was learned, or educated, in all the wisdom of the Egyptians—it stands to reason, being raised in the palace of the king. Les points out that Scripture gives us the knowledge that Moses was the top man in Egypt under Pharaoh, highly educated, with a lot of power, mighty in word and deeds. Les also notes the breakdown of Moses' life into segments of 40: 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, which we only get in Acts chapter 7.
And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds.
