G3153–ματαιότης–mataiotēs

for to vanity was the creation made subject -- not of its will, but because of Him who did subject `it' -- in hope,

ματαιότητι mataiotēti “futility”

This, then, I say, and I testify in the Lord; ye are no more to walk, as also the other nations walk, in the vanity of their mind,

ματαιότητι mataiotēti “[the] futility”

for overswellings of vanity speaking, they do entice in desires of the flesh -- lasciviousnesses, those who had truly escaped from those conducting themselves in error,

ματαιότητος mataiotētos “of vanity”
