'Purely' in the Bible

My words shall be of the uprightness of my heart, and my lips shall utter knowledge purely.

And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin:

But if our unrighteousness demonstrates the righteousness of God, what shall we say? God is not wrong to inflict His wrath [on us], is He? (I am speaking in purely human terms.)

So when I planned this, was I irresponsible? Or what I plan, do I plan in a purely human way so that I say “Yes, yes” and “No, no” simultaneously?

From now on, then, we do not know anyone in a purely human way. Even if we have known Christ in a purely human way, yet now we no longer know Him in this way.

the one, indeed, of rivalry the Christ do proclaim, not purely, supposing to add affliction to my bonds,

but those out of contention, announce the Christ, not purely, supposing to arouse tribulation for my bonds.
