Colossians 3:9

Lie not one to another - Do not deceive each other; speak the truth in all your dealings; do not say, "My goods are so and so," when you know them to be otherwise; do not undervalue the goods of your neighbor, when your conscience tells you that you are not speaking the truth. It is naught, it is naught, saith the buyer; but afterwards he boasteth; i.e. he underrates his neighbour's property till he gets him persuaded to part with it for less than its worth; and when he has thus got it, he boasts what a good bargain he has made. Such a knave speaks not truth with his neighbor.

Ye have put off the old man - See the notes on Romans 6:6; and particularly on Romans 13:11-14 (note). Ye have received a religion widely different from that ye had before; act according to its principles.

Lie not one to another - Notes, Ephesians 4:25.

Seeing that ye have put off the old man with his deeds - Your former corrupt and evil nature; Notes, Ephesians 4:22. The reason for putting away lying, stated in Ephesians 4:25, is, that we "are members one of another" - or are brethren. The reason assigned here is, that we have put off the old man with his deeds. The sense is, that lying is one of the fruits of sin. It is that which the corrupt nature of man naturally produces; and when that is put off, then all that that nature produces should be also put off with it. The vice of lying is a universal fruit of sin, and seems to exist everywhere where the gospel does not prevail; compare the notes at Titus 1:12. There is, perhaps, no single form of sin that reigns so universally in the pagan world.
