The Kitvei HaKodesh brings us a series of some special ro set-apart Scriptures which are commonly called the Bible, or Book of books, in which we take it we can find God speaking by the means of his messengers and prophets. It was under His direction people wrote what god requested to write down.
By that spoken Word people shall have to come to believe in Jehovah, the Only One True God (The God above all gods).
“And God spake all these words, saying,” (Ex 20:1 AV)

It was God Who by the power of His Ruach got people to write down His Words:

“For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.” (1Th 2:13 AV)
“20 Knowing this first, that no prophecy of the scripture is of any private interpretation. 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. {in old time: or, at any time } (2Pe 1:20-21 AV)
“1 Now these be the last words of David. David the son of Jesse said, and the man who was raised up on high, the anointed of the God of Jacob, and the sweet psalmist of Israel, said, 2 The Spirit of the LORD spake by me, and his word was in my tongue.” (2Sa 23:1-2 AV)
