Exod 2:7-9

7Then his sister said to Pharaoh's daughter, “Shall I go and get you a nurse from the Hebrew women to nurse the child for you?”8Pharaoh's daughter said to her, “Yes.” So the girl went and called the child's mother.9Pharaoh's daughter said to her, “Take this child and nurse it for me, and I will give you your wages.” So the woman took the child and nursed it.
