Exodus 8:20

And the daughter of Pharaoh came down to bathe at the Nile, with her young women walking alongside the Nile; and she saw the ark among the reeds and sent her maidservant, and she took it to her.

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

And Yahweh said to Moses, “Rise up early in the morning and stand before Pharaoh, and you shall say to him, ‘Thus says Yahweh, the God of the Hebrews, “Let My people go, that they may serve Me.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.
