Exodus 2:1-3 (NIV)

1 Now a man of the tribe of Levi married a Levite woman,

2 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.

3 But when she could hide him no longer, she got a papyrus basket[a] 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.
