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 2:11

2:11 In him you also were circumcised – not, however, with a circumcision performed by human hands, but by the removal of the fleshly body, that is, through the circumcision done by Christ.
