Acts 7:23, 30, 36

“Now when he was forty years old, it came into his heart to visit his brethren, the children of Israel.

“And when forty years had passed, an Angel of the Lord appeared to him in a flame of fire in a bush, in the wilderness of Mount Sinai.

He brought them out, after he had shown wonders and signs in the land of Egypt, and in the Red Sea, and in the wilderness forty years.
