Kolose 4:6

4:6 Let your speech always be gracious, seasoned with salt, so that you may know how you should answer everyone.

Kolose 2:18

2:18 Let no one who delights in humility and the worship of angels pass judgment on you. That person goes on at great lengths ¹  about what he has supposedly seen, but he is puffed up with empty notions by his fleshly mind. ² 

Kolose 3:9

3:9 Do not lie to one another since you have put off the old man with its practices

[2:18]  ¹ tn For the various views on the translation of ἐμβατεύων (embateuwn), see BDAG 321 s.v. ἐμβατεύω 4. The idea in this context seems to be that the individual in question loves to talk on and on about his spiritual experiences, but in reality they are only coming out of his own sinful flesh.

[2:18]  ² tn Grk “by the mind of his flesh.” In the translation above, σαρκός (sarkos) is taken as an attributive genitive. The phrase could also be translated “by his sinful thoughts,” since it appears that Paul is using σάρξ (sarx, “flesh”) here in a morally negative way.
