“There shall be a great cry throughout all the land of Egypt, such as there has never been, nor ever will be again” (v6). Moses urged Pharaoh to let the Israelites leave Egypt to worship the Lord “in the wilderness.” When Pharaoh refused, plagues came upon Egypt, getting progressively worse, as God demonstrated His power to those who worshipped false gods. Finally, when Pharaoh still refused to grant freedom to the Israelites, God revealed His power over life and death.
“Yet one plague more …” (v1). God urges us to “choose life,” to love and obey the Life-giver, because rebellion opens the door to death - separation from the One who loves us.
