Exodus 2:1-4 ESV
Now a man from the house of Levi went and took as his wife a Levite woman. The woman conceived and bore a son, and when she saw that he was a fine child, she hid him three months. When she could hide him no longer, she took for him a basket made of bulrushes and daubed it with bitumen and pitch. She put the child in it and placed it among the reeds by the river bank. And his sister stood at a distance to know what would be done to him.
