Matthew Henry's Complete Bible Commentary

Verses 11—13

The prisoners being found guilty by their own confession, besides the personal and infallible knowledge of the Judge, and nothing material being offered in arrest of judgment, God immediately proceeds to pass sentence; and, in these verses, he begins (where the sin began) with the serpent. God did not examine the serpent, nor ask him what he had done nor why he did it; but immediately sentenced him, 1. Because he was already convicted of rebellion against God, and his malice and wickedness were notorious, not found by secret search, but openly avowed and declared as Sodom’s. 2. Because he was to be for ever excluded from all hope of pardon; and why should any thing be said to convince and humble him who was to find no place for repentance? His wound was not searched, because it was not to be cured. Some think the condition of the fallen angels was not declared desperate and helpless, until now that they had seduced man into the rebellion. MHBCC 4.30
