Exodus 10:16

Then Pharaoh called for Moses and Aaron in haste; and he said, I have sinned against the LORD your God, and against you.

Ver. 16. I have sinned against the Lord.] A fair confession, but forced and extorted. Thus the toad, if beaten on the belly, will vomit up his venom, and the malefactor on the rack will utter all. But as water heated, if taken off the fire will soon return to its natural coldness, yea, become colder after heating than before; a so hypocrites' heats are not kindly, from the Spirit, but violent, from the outward fire of God's judgments: therefore when that is out, these are gone.
