The Ninth Blow: Darkness
10:21 The Lord said to Moses, “Extend your hand toward heaven so that there may be darkness over the land of Egypt, a darkness so thick it can be felt.”
10:22 So Moses extended his hand toward heaven, and there was absolute darkness throughout the land of Egypt for three days.
10:23 No one could see another person, and no one could rise from his place for three days. But the Israelites had light in the places where they lived.
