Exodus 2:2-4

2The woman became pregnant and gave birth to a son; when she saw that he was beautiful, she hid him for three months.

3But when she could no longer hide him, she got a papyrus basket for him and coated it with asphalt and pitch. She placed the child in it and set it among the reeds by the bank of the Nile.

4Then his sister stood at a distance in order to see what would happen to him.
