Exodus 2:3, 4, 5

But when she could no longer hide him, she got a basket made of papyrus reeds and waterproofed it with tar and pitch. She put the baby in the basket and laid it among the reeds along the bank of the Nile River.

The baby’s sister then stood at a distance, watching to see what would happen to him.

Soon Pharaoh’s daughter came down to bathe in the river, and her attendants walked along the riverbank. When the princess saw the basket among the reeds, she sent her maid to get it for her.
