Colossians 3:8

As we are to mortify inordinate appetites, so we are to mortify inordinate passions (Col 3:8): But now you also put off all these, anger wrath, malice; for these are contrary to the design of the gospel, as well as grosser impurities; and, though they are more spiritual wickedness, have not less malignity in them. The gospel religion introduces a change of the higher as well as the lower powers of the soul, and supports the dominion of right reason and conscience over appetite and passion. Anger and wrath are bad, but malice is worse, because it is more rooted and deliberate; it is anger heightened and settled. And, as the corrupt principles in the heart must be cut off, so the product of them in the tongue; as blasphemy, which seems there to mean, not so much speaking ill of God as speaking ill of men, giving ill language to them, or raising ill reports of them, and injuring their good name by any evil arts, - filthy communication, that is, all lewd and wanton discourse, which comes from a polluted mind in the speaker and propagates the same defilements in the hearers, - and lying: Lie not one to another (Col 3:9), for it is contrary both to the law of truth and the law of love, it is both unjust and unkind, and naturally tends to destroy all faith and friendship among mankind.

But now--that ye are no longer living in them. ye also--like other believers; answering to "ye also" (Col 3:7) like other unbelievers formerly. put off--"Do ye also put away all these," namely, those just enumerated, and those which follow [ALFORD]. anger, wrath--(See on Eph 4:31). blasphemy--rather, "reviling," "evil-speaking," as it is translated in Eph 4:31. filthy communication--The context favors the translation, "abusive language," rather than impure conversation. "Foul language" best retains the ambiguity of the original.
