1 Corinthians 7:20LXX

18Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.

19Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.

20Let every man abide in the same calling wherein he was called.

21Art thou called a servant? care not for it: but if thou mayest be made free, use rather.

22For he that is called in the Lord, a servant, is the Lord's freeman: likewise also he that is called, free, is Christ's servant.
