Exodus 7

⁸ Yahweh spoke to Moses and Aaron.

¹³ Pharaoh's heart turned to stone. He would not listen. Just like Yahweh said.

¹⁴ Yahweh said to Moses, "Pharaoh's heart is locked tight. He will not let my people go."

¹⁹ Yahweh said to Moses, "Tell Aaron this: Take your stick. Hold your hand out over every drop of water in Egypt. Rivers, streams, ponds, pools. Every jar and every pot. It will all turn to blood."

²² But the Egyptian wizards did the same thing with their dark power. Pharaoh's heart got even harder. He would not listen. Just like Yahweh said.
