Exodus 2:1–10 describes the birth and early life of Moses. His mother defies the order to kill Hebrew boys and hides her son. Once he becomes too old to conceal, she places him in a basket on the Nile. Apparently, this was a deliberate attempt to have Moses adopted, as Moses’ older sister is stationed nearby, watching. Pharaoh’s daughter finds the baby, and winds up hiring Moses’ own mother to be his wet nurse. Once weaned, Moses is sent back to the Egyptian princess, gaining the benefits of a royal education and upbringing.
