G1397–δουλεία–douleia

for ye did not receive a spirit of bondage again for fear, but ye did receive a spirit of adoption in which we cry, `Abba -- Father.'

δουλείας douleias “of bondage”

that also the creation itself shall be set free from the servitude of the corruption to the liberty of the glory of the children of God;

δουλείας douleias “bondage”

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

δουλείαν douleian “slavery”

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

δουλείας douleias “of slavery”

and might deliver those, whoever, with fear of death, throughout all their life, were subjects of bondage,

δουλείας. douleias “to slavery.”
