And Moses and Aaron came in unto Pharaoh, and said unto him, Thus saith the LORD God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.
3. And Moses and Aaron came in. Moses now relates how, at God’s command, he tried whether Pharaoh’s heart, after so many experiments, would be bent to obedience out of fear of the new punishment which impended. But by this proof his impiety was better known, since, although he saw his kingdom deprived of a part of its corn, he fears not what is denounced...
God tells me plainly what He means to do: display His power over all creatures and over Satan's kingdom through these plagues, so that what I write will teach the world's end that sin provokes the Lord to jealousy. Pharaoh's refusal to humble himself before God, the God even of despised slaves, is the very sin that justly calls down His judgment on princes.
