'Changed' in the Bible

Go to Pharaoh in the morning. Look, [he is] going out to the water, and you must wait to meet him on the bank of the Nile, and you must take in your hand the staff that was changed into a snake.

Thus says Yahweh, "By this you will know that I [am] Yahweh. Look, I [am about to] strike with the staff that is in my hand the water that is in the Nile, and it will be changed to blood.

And Moses and Aaron did so, as Yahweh had commanded, and he raised the staff and struck the water that was in the Nile before the eyes of Pharaoh and before the eyes of his servants, and all of the water that was in the Nile was changed to blood.

And it was told to the king of Egypt that the people fled, and the heart of Pharaoh was changed and [that of] his servants toward the people, and they said, "What [is] this we have done, that we have released Israel from serving us!"
