'Itself' in the Bible

What follows? Is the Law itself a sinful thing? No, indeed; on the contrary, unless I had been taught by the Law, I should have known nothing of sin as sin. For instance, I should not have known what covetousness is, if the Law had not repeatedly said, "Thou shalt not covet."

But sin, finding an opportunity through the commandment [to express itself] produced in me every kind of coveting and selfish desire. For without the Law sin is dead [the recognition of sin is inactive].

And the commandment, which was for life, was found, as to me, itself to be unto death:

So then, the Law itself is holy, and the rule is holy, just, and good.

For the mind-set of the flesh is hostile to God because it does not submit itself to God’s law, for it is unable to do so.

The Spirit itself beareth witness with our spirit, that we are the children of God:

Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.

Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.

I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
