Book of Jubilees which some refer to as little genesis says God created spirits on the first day.
so the following verses which say spirit of man are mistranslations?
The Book of Jubilees is part of those books called the pseudepigrapha (meaning “false writings”), and include such books as “The Assumption of Moses,” “The Apocalypse of Ezra” and the “Book of Jubilees.” Some 47 works in all, these books reportedly were written between 200 B.C.E. and 200 C.E, after the death of the apostles.
There is a reason why they are NOT part of the Bible canon.
Prof. James H. Charlesworth of Duke University, states, concerning the pseudepigrapha: “Among the more striking discoveries [in the pseudepigrapha] are a pronounced belief in astrology and a luxuriant angel worship which, in the view of some scholars, borders on polytheism.” If these books are promoting things that other parts of the Bible condemn, then this is the reason why they are not included. Non-canonical books cannot shape our beliefs.
Pro 20:27 The spirit of man is the candle of the LORD, searching all the inward parts of the belly.
Or an alternative rendering...
"The breath of a man is the lamp of Jehovah, Searching through his innermost being."
The word translated "spirit" in this verse is
"nĕshamah" which means "breath". Nothing to do with an invisible spirit. God searches through man whilst he is alive...breathing.
Ecc 3:21 Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth?
The difference between man and animals is that our "breath" returns to God who is in heaven.....and it can be returned to us in the resurrection, re-animating a new body....but animals have no other life other than what they live now....once they go back to the dust of the earth, there is no returning of their spirit .(breath) (Ecclesiastes 3:19-20)
Zec 12:1 The burden of the word of the LORD for Israel, saith the LORD, which stretcheth forth the heavens, and layeth the foundation of the earth, and formeth the spirit of man within him.
Or in plain English...
"A pronouncement:
“The word of Jehovah concerning Israel,” declares Jehovah,
The One who stretched out the heavens,
Who laid the foundation of the earth,
And who formed the spirit [breath] of man within him."
This has nothing to do with a living spirit of man, created by God that is separate from the body. God gave man his "breath"...it is what made Adam a "soul".
Psalm 146:4 says...
"His spirit leaves, he returns to his soil; on that day, his thoughts are lost." (Tanakh)
The word "spirit" here is "
ruwach" which also means....
"wind, breath, mind, spirit." It "leaves" when the last breath is breathed and the soul dies. No thinking processes survive death, as Ecclesiastes 9:10 makes clear.
I can see that you are a serious student of the Bible but may I suggest that a bit more study in the languages of the Bible might be in order, and that you might rely less on the erroneous translation that you insist on using....it appears to be leading you down pathways that are not in keeping with the Bible's overall message.
1Co 2:11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
The spirit of man can also mean his disposition...much like you can say that a horse is "spirited". Humans have a spirit in them too. People can be meek or headstrong.
You tend to see only one meaning to the words used in your archaic Bible. That is a shame because that is not how the languages of the Bible work.
God is a Spirit...he also has Holy Spirit which is the means by which he accomplished his will. It is given in direct proportion to what humans need if they are carrying out part of his purpose. God gave it to Jesus at his baptism, the disciples received it at Pentecost...it is God's power given to humans to accomplish whatever his will dictates.
also what would be the understanding of spirit in Ecc 11:5?
Ecc 11:5 As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
Again in plain English....
"Just as you do not know how the spirit operates in the bones of the child inside a pregnant woman, so you do not know the work of the true God, who does all things."
When Solomon wrote that, no man knew how the body of an infant formed in its mother's womb.....but they knew that humans and in fact all creation were a product of God's spirit.....just as they were ignorant of those facts back then, so humans even today have no idea how God works his wonders in his own creation....and how the outworking of his original purpose for man and this earth will play out....but its all there in the Bible if we don't allow our pre-conceived ideas get in the way.
