Albert Barnes Commentary Colossians 3:9

"lie not one to another; seeing that ye have put off the old man with his doings," — Colossians 3:9 (ASV)

Lie not one to another. (See Barnes on Ephesians 4:25).

Seeing that ye have put off the old man with his deeds. This refers to your former corrupt and evil nature. (See Barnes on 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 nature is put off, then all that it produces should also be put off with it. The vice of lying is a universal fruit of sin and seems to exist everywhere the gospel does not prevail. (Compare to Barnes on Titus 1:12).

There is, perhaps, no single form of sin that reigns so universally in the non-Christian world.
