Exodus 17:1-7; the Book of Exodus is a profound book which teaches us about Yahweh's Faithfulness to increasingly unfaithful Israel. He saved from slavery and just a few chapters later the people bring a Covenant Lawsuit against Moses and Yahweh, charging them with treason. If the people are justified in their charge then Yahweh should die, if they are not then they take the penalty for their unjust charge. How will Yahweh maintain his Holiness and his Mercy? Who is going to die?
