'Servitude' in the Bible

so also we, when we were babes, under the elements of the world were in servitude,

But then, indeed, not having known God, ye were in servitude to those not by nature gods,

and now, having known God -- and rather being known by God -- how turn ye again unto the weak and poor elements to which anew ye desire to be in servitude?

which things are allegorized, for these are the two covenants: one, indeed, from mount Sinai, to servitude bringing forth, which is Hagar;

for this Hagar is mount Sinai in Arabia, and doth correspond to the Jerusalem that now is, and is in servitude with her children,

In the freedom, then, with which Christ did make you free -- stand ye, and be not held fast again by a yoke of servitude;
