Exodus 2:10

The mother kept the child probably till he was weaned, which would be two or perhaps three years. He was then adopted by Pharaoh's daughter and would receive the education of an Egyptian prince. St. Stephen says that 'Moses was learned in all the wisdom of the Egyptians and was mighty in words and in deeds.' Josephus says that Moses became general of the Egyptian army and defeated the Ethiopians, also that Pharaoh's daughter, having no child of her own, intended to make him her father's successor. The name Moses, which she gave him, is an Egyptian, not a Hebrew word, and means 'child' or 'son.' It appears in names like Rameses, Thothmes, etc. It is only therefore by a play upon words that it is connected with the Hebrew word mashah, 'to draw out.'
