Exodus 10
1 Yahweh said to Moses, "Go back to Pharaoh. I locked his heart. I did the same to his officials. I did this so I can show my power right in front of them."
16 Pharaoh ran. "I did wrong! I did wrong to Yahweh your God! I did wrong to you!"
18 Moses walked out and cried to Yahweh.
21 Yahweh said to Moses, "Raise your hand to the sky. Bring darkness over Egypt. Darkness so thick you can touch it."
24 Pharaoh called Moses. "Go. Pray to Yahweh. Take your kids. But the animals stay."
