Exodus 2:3-5

Amplified Bible

³ When she could no longer hide him, she got him a basket (chest) made of papyrus reeds and covered it with tar and pitch [making it waterproof]. Then she put the child in it and set it among the reeds by the bank of the Nile. ⁴ And his sister [Miriam] stood some distance away to find out what would happen to him.

⁵ Now the ^[a]daughter of Pharaoh came down to bathe at the Nile, and [she, together with] her maidens walked along the river’s bank; she saw the basket among the reeds and sent her maid [to get it], and she brought it to her.
