2 Peter 2:19

Promise them liberty. — A specimen of the “great swelling words” — loud, high-sounding talk about liberty. The doctrines of Simon Magus, as reported by Irenæus (I., chap. xxiii. 3) and by Hippolytus (Refut. VI., chap. xiv.), show us the kind of liberty that such teachers promised — being “freed from righteousness” to become “the slaves of sin.”

Servants of corruption. — Better, bond-servants, or slaves of corruption. Our translators have often done well in translating the Greek word for “slave” by “servant” (see Note on 2 Peter 1:1), but here the full force of the ignominious term should be given. Tyndale, Cranmer, and Geneva have “bond-servants;” Rheims “slaves.” (Comp. “bondage of corruption,” Romans 8:21.)

Brought in bondage. — Or, enslaved. We seem here to have an echo of John 8:34 (see Notes there): “Every one who continues to commit sin is the slave of sin,” words which St. Peter may have heard. Comp. Romans 6:16, which the writer may also have had in his mind. There is nothing improbable in St. Peter being well acquainted with the Epistle to the Romans during the last years of his life; the improbability would rather be in supposing that he did not know it.
