Exodus 7:13-15

LITV(i) 13 And the heart of Pharaoh was hardened, and he did not listen to them, as Jehovah had said. 14 And Jehovah said to Moses, The heart of Pharaoh is heavy; he refuses to send away the people. 15 Go to Pharaoh in the morning. Behold, he is about to go out to the water. And you stand to meet him on the lip of the river. And you shall take in your hand the staff that was turned into a snake.
