But when she could no longer hide him, she got him a papyrus basket and coated it with tar and pitch. Then she placed the child in the basket and set it among the reeds along the bank of the Nile. / Soon the daughter of Pharaoh went down to bathe in the Nile, and her attendants were walking along the riverbank. And when she saw the basket among the reeds, she sent her maidservant to retrieve it.
