'Elemental' in the Bible

So also we, when we were children, we were enslaved under the elemental spirits of the world.

But now, [because you] have come to know God, or rather have come to be known by God, how can you turn back again to the weak and miserable elemental spirits? Do you want to be enslaved to them all over again?

Beware lest {anyone take you captive} through philosophy and empty deceit, according to {human tradition}, according to the elemental spirits of the world and not according to Christ,

If you have died with Christ to the elemental spirits of the world, why do you submit [to them] as [if] living in the world?
