Reading through Exodus, I always take a moment to pause at Pharaoh’s response after the locust plague. He wouldn’t let the Israelites go so God sent a plague of locust so bad that the land was literally black in a deep cover of them. After seeing this, Pharaoh called for Moses and said, “I have sinned against the LORD your God and against you. Now therefore, please forgive my sin only this once, and entreat the LORD your God, that He may take away from me this death only.”
I pause here because Pharaoh was only interested in being forgiven just enough for the plague to go away. He asked to only be forgiven “this once.” He had no intent to truly repent or seek forgiveness. He just wanted the plague gone. It is a pretty pathetic grasp at relief, if you think about it.
