Exodus 9:1

1.Then the Lord said. No complaint or expostulation of Moses is here recounted; and it is possible that he was quiet and silent, whilst God foresaw what it was necessary to do, and even commanded what He would have done. But since he only gives a brief summary of occurrences, we may probably conjecture that, as the evil grew worse, he had recourse from time to time to the remedy. In the denunciation, “the Lord God of the Hebrews” is no unmeaning repetition, that Pharaoh may learn that he, whom he thought to have repelled in the abundance of his pride, was still in the field against him. For God insults his ferocity, and by setting forth his name contemptuously defies his wrath. We have already said that Pharaoh is convicted of sacrilege, both in his oppression of God’s people and in defrauding God Himself of His due honor; therefore those words, “Let my people go, that they may serve me,” have the force of aggravating his sin.
