Holy Scriptures

The word inspiration is used twice in the KJV as far as I can find once by Elihu in the old testament, and once by Paul in the new testament.
Job 32:8   But [there is] a spirit in man: and the inspiration of the Almighty giveth them understanding. (  it is the spirit* in a man, the breath of the Almighty, that gives him understanding.)
Job 32:9  Great men are not [always] wise: neither do the aged understand judgment.
Job 32:10  Therefore I said, Hearken to me; I also will shew mine opinion.
 Job 32:18   For I am full of matter, the spirit within me constraineth me
We know that Elihu is not talking about the holy ghost/comforter, because it was not given as of then.

2Ti 3:16  All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
This is the information given Timothy, by Paul.keeping within context of the conversation leading up to this, we see Paul could have only been talking about Old Testament scripture.
2Ti 3:14  But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned [them];
2Ti 3:15   And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.

Since the New Testament was not yet in print,when Timothy was a child, we know Paul was speaking of Old Testament holy scriptures. It would be hard to make the jump that Paul was including any writings that came after  his speaking to Timothy.

 The word scripture appears 32 times in the KJV all 32 times refer to old testament scripture written by the prophets inspired/moved by God.

Let's look at what Peter said about scripture.

2Pe 1:20  Knowing this first, that no prophecy of the scripture is of any private interpretation.
2Pe 1:21  For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost.

Inspiration

More than once Paul said he spoke of his own volition, not a commandment of God.
so that pretty much denied that every word in the bible came by inspireation/ God's
breath.
1Cr 7:6  But I speak this by permission, [and] not of commandment.
1Cr 7:25  Now concerning virgins I have no commandment of the Lord: yet I give
my judgment, as one that hath obtained mercy of the Lord to be faithful.
There are many places in Paul's letters  where it is apparent he is speaking on his
own.
unless you are willing to say Paul did not know of which he spoke, you can not
contradict what he said. Jesus Christ spoke the words of God, as Paul said he did
not always do so.
Unless you wish to contradict what Luke said about where he got his information that
he wrote about in two books, you can not say Lukes writings were whispered to him
by the :holy ghost"
Luk 1:1  Forasmuch as many have taken in hand to set forth in order a declaration
of those things which are most surely believed among us,
Luk 1:2   Even as they delivered them unto us, which from the beginning were
eyewitnesses, and ministers of the word;
Luk 1:3 It seemed good to me also, having had perfect understanding of all things
from the very first, to write unto thee in order, most excellent Theophilus,
Luk 1:4  That thou mightest know the certainty of those things, wherein thou hast
been instructed.
If you look at Lk 1:2 it is evident that Luke is speaking of the Apostles who were
with Jesus.Yes the Apostles had the advantage of calling upon the "holy ghost"/
comforter when they needed to do so, but even that does not mean every word they
wrote was breathed into their ear, by the spirit.
That said I believe every writer in the bible was inspired to do what they did, inspired
by their belief, inspired in the meaning influenced.
