Exodus 2:1-3

Now a man of the tribe of Levi married a Levite woman, and she became pregnant and gave birth to a son. When she saw that he was a fine child, she hid him for three months. But when she could hide him no longer, she got a papyrus basket for him and coated it with tar and pitch. Then she placed the child in it and put it among the reeds along the bank of the Nile.
