1st Corinthians 7:21

18 being circumcised -- was any one called? let him not become uncircumcised; in uncircumcision was any one called? let him not be circumcised;

19 the circumcision is nothing, and the uncircumcision is nothing -- but a keeping of the commands of God.

20 Each in the calling in which he was called -- in this let him remain;

21 a servant -- wast thou called? be not anxious; but if also thou art able to become free -- use [it] rather;

22 for he who [is] in the Lord -- having been called a servant -- is the Lord`s freedman: in like manner also he the freeman, having been called, is servant of Christ:

23 with a price ye were bought, become not servants of men;

24 each, in that in which he was called, brethren, in this let him remain with God.
