'Bondman' in the Bible

For do I now seek to satisfy men or God? or do I seek to please men? If I were yet pleasing men, I were not Christ's bondman.

There is no Jew nor Greek; there is no bondman nor freeman; there is no male and female; for ye are all one in Christ Jesus:

Now I say, As long as the heir is a child, he differs nothing from a bondman, though he be lord of all;

So thou art no longer bondman, but son; but if son, heir also through God.
