Colossians 3:9-11 (ESV)
9 Do not lie to one another, seeing that you have put off the old self with its practices
10 and have put on the new self, which is being renewed in knowledge after the image of its creator.
11 Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free, but Christ is all, and in all.
