Colossians 2:8

2:8 Be careful not to allow anyone to captivate you through an empty, deceitful philosophy that is according to human traditions and the elemental spirits of the world, and not according to Christ.

Colossians 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 about what he has supposedly seen, but he is puffed up with empty notions by his fleshly mind.

Colossians 2:23

2:23 Even though they have the appearance of wisdom with their self-imposed worship and false humility achieved by an unsparing treatment of the body – a wisdom with no true value – they in reality result in fleshly indulgence.
