And. the Lord said... — The series of the nine wonders wrought by Moses and Aaron is terminated by this short summary, of which the main points are — (1) God had said (Exodus 4:21) that the miracles would fail to move Pharaoh; (2) He had assigned as the reason for this failure His own will that the wonders should be multiplied (Exodus 7:3); (3) the miracles had now been wrought; (4) Pharaoh had not been moved by them; (5) God had hardened his heart, as a judgment upon him, after he had first himself hardened it. The result had been a series of manifestations calculated to impress the Israelites with a sense of God’s protecting care, the Egyptians and the neighbouring nations with a sense of His power to punish.
