'Brink' in the Bible

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.

Go to Pharaoh in the morning as he is going out to the water, and wait for him on the bank of the Nile; and you shall take in your hand the staff that was turned into a serpent.
