Exodus 2:7-9

Then said his sister to Pharaoh's daughter, Shall I go and call to thee a nurse of the Hebrew women, that she may nurse the child for thee?

And Pharaoh's daughter said to her, Go. And the maid went and called the child's mother.

And Pharaoh's daughter said unto her, Take this child away, and nurse it for me, and I will give thee thy wages. And the woman took the child, and nursed it.
