10So Moses and Aaron went to Pharaoh and did just as the LORD commanded. Aaron threw his staff down in front of Pharaoh and his officials, and it became a snake.
15Go to Pharaoh in the morning as he goes out to the river. Confront him on the bank of the Nile, and take in your hand the staff that was changed into a snake.
16Then say to him, 'The LORD, the God of the Hebrews, has sent me to say to you: Let my people go, so that they may worship me in the wilderness. But until now you have not listened.
17This is what the LORD says: By this you will know that I am the LORD: With the staff that is in my hand I will strike the water of the Nile, and it will be changed into blood.
19The LORD said to Moses, "Tell Aaron, 'Take your staff and stretch out your hand over the waters of Egypt--over the streams and canals, over the ponds and all the reservoirs--and they will turn to blood.' Blood will be everywhere in Egypt, even in vessels of wood and stone."
20Moses and Aaron did just as the LORD had commanded. He raised his staff in the presence of Pharaoh and his officials and struck the water of the Nile, and all the water was changed into blood.
22But the Egyptian magicians did the same things by their secret arts, and Pharaoh's heart became hard; he would not listen to Moses and Aaron, just as the LORD had said.
