Moses was trained in all the wisdom of the Egyptians, and he was powerful in his words and in his deeds.
In context
20At that time Moses was born, and he was beautiful in God’s sight. For three months he was raised in his father’s house; 21and when he was abandoned, Pharaoh’s daughter took him up and raised him as her own son. 22Moses was trained in all the wisdom of the Egyptians, and he was powerful in his words and in his deeds. 23When he reached the age of forty, it came into his heart to visit his brothers, the sons of Israel. 24Seeing one of them wronged, he came to his defense and paid back the man who was crushing him, striking down the Egyptian.
