Exodus 2:3-5

3But when she could no longer hide him, she took a basket of papyrus reeds, coated it with tar and pitch, put the child inside, and laid it in the reeds by the bank of the Nile.

4His sister stood off at a distance to see what would happen to him.

5Then the daughter of Pharaoh came down to bathe, while her maidens walked along by the riverside. When she saw the basket among the reeds, she sent her handmaiden to fetch it.
