'Servants' in the Bible

have ye not known that to whom ye present yourselves servants for obedience, servants ye are to him to whom ye obey, whether of sin to death, or of obedience to righteousness?

and thanks to God, that ye were servants of the sin, and -- were obedient from the heart to the form of teaching to which ye were delivered up;

and having been freed from the sin, ye became servants to the righteousness.

In the manner of men I speak, because of the weakness of your flesh, for even as ye did present your members servants to the uncleanness and to the lawlessness -- to the lawlessness, so now present your members servants to the righteousness -- to sanctification,

for when ye were servants of the sin, ye were free from the righteousness,

And now, having been freed from the sin, and having become servants to God, ye have your fruit -- to sanctification, and the end life age-during;

for because of this also pay ye tribute; for servants of God they are, on this very thing attending continually;
