1 Corinthians 7:21-23
New International Version
21 Were you a slave when you were called? Don’t let it trouble you—although if you can gain your freedom, do so. 22 For the one who was a slave when called to faith in the Lord is the Lord’s freed person;(A) similarly, the one who was free when called is Christ’s slave.(B) 23 You were bought at a price;(C) do not become slaves of human beings.
