The Passover is the climax in a titanic battle that is waged between the God of Israel and the gods of Egypt. In the plagues of Egypt there are four stages to the battle, with three trios of judgment. The sequence of natural disasters is laden with theological overtones; it is as if all creation is becoming unhinged. The critical question is: who is in charge? Pharaoh and his magicians or Moses? Pharaoh’s gods or the God of Israel? Lurking in the background is Pharaoh’s question at the beginning of this battle: ‘Who is Yahweh that I should listen to his voice’ (Exodus 5:2)? Yahweh is none other than the Creator (Elohim).
