1 Corinthians 7:
18 Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.
19 Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.
20 Let every man abide in the same calling wherein he was called.
21 Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather.
22 For he that is called in the Lord, being a servant, is the Lord’s freeman: likewise also he that is called, being free, is Christ’s servant.
23 Ye are bought with a price; be not ye the servants of men.
