"Prophesy"
[בא] BA = come.
[נבא] NBA = Ni-VA = (nif-al) simple-passive of come
= that which is coming, impending.
[נבא] then becomes a nifal passive derivative "root word" - an example where some soresh types are actually derivatives of more fundamental soresh types.
[באי] B_i = imperative/cohortative towards 2nd person feminine
= instruct you-girl to come
[נבאי] NaV_i = collective/intensive imperative/cohortative towards 2nd person feminine
= to declare about that which is coming
[נביא] NaV_i = plural 1st person uncompleted causative
= we shall cause it to come
= translated as "prophet"
[הנבא] HiNaVe = imperative/cohortative towards 2nd person masc passive-derivative.
= instructively/cohortatively speak to that which is coming.
"Flow Vector"
Since [רוח] is taken to mean spirit, wind, direction, or a flowing entity, I shall reference the word as flow vector.
Inversive-vav theory is wrong
Read the 2nd half of here for my explanation why inversive-vav theory is plain wrong. It is wrong, and therefore it is inconsistently applied - we pick and choose when to apply it.
If we accept that inversive-vav theory is wrong and bring consistency to the reading of the Hebrew, it completely overturns the situation, where what were thought of as prophecy are merely subjunctives, propositions, possibilities.
Translation of Ezekiel 37:9 like many verses in the Bible, suffers from this inconsistency within one sentence itself. So let's not even apply this defective theory anywhere.
Ezekiel 37:9
NOTICE I bolded the instances of "come"
ויאמר אלי
And-then he says to me
הנבא אל הרוח
Instruct-its-coming to the vector
הנבא בן אדם
Instruct-its-coming son of man
אל הרוח כה
to the vector thus
אמר אדני יי
Said my Lord-Identity
מארבע רוחות
from four vectors
באי ופחי בהרוגים האלה
Come and you flow/cover/envelop in/upon those killed
ויהיו
And they shall live
Was he told to "prophecy" ?
You be the judge - by reading the plain Hebrew, uncontaminated with doctrinal predilection.
AFAIAC, this is what the verse meant ...
The LORD then says to me, to instruct the vector, he says "son of man, instruct the vector thus": You should/shall come from four directions, and immerse those who had been killed so that they shall live.
"Yahweh" is pejorative
Also, let me clarify that I belong to the school of thought that says the Name of the LORD as written in Hebrew should not be pronounced, or even transliterated into a form that would aid or suggest verbal pronunciation of any form.
I go further, by holding that the tetra-alefbetic Name is the multidimensional Identity of the LORD.
In modern communications (developed by Churchill-Roosevelt or their engineers to avoid German decryption), to avoid the necessity and vulnerabilities of transmitting passwords, you would use a token pair of encryption keys to communicate. Unlike Churchill-Roosevelt, the counterparts of each modern encryption pairs need not be the same, to be able to IDENTIFY and reciprocate each other and decrypt encrypted messages on both sides.
The higher the degrees-of-freedom (dimensions), the more complex the encryption.
The Identity of the LORD is a high-dimension Identity. And the Identity is listening for the counterpart signature to verify/validate themselves.
Therefore, frequent Evangelical Christian accusations of Jews having forgotten how to verbally pronounce the Name is not only deliberately vindictive, they also demonstrate their abject lack in understanding the reason for the Name/Identity of G'd.
Some accuse us of Gnosticism by our reasoning. But, gnosticism is the problem of Christianity, and it is futile to transference that problem onto Jews.
yahweh is merely verbalization of the alphabetic sequence, and is not in any way the actual Identity of G'd. To say that yahweh is the complete name of the LORD is foolhardy and pejorative.
Who is the vector ?
Perhaps the vector that come from four directions is the reciprocal vector of the Identity of G'd. It is the collective spirit of the human race.
The collective spirit of the human race is told to play-god, in this Ezekiel passage. Then says the LORD to tell the dead thus - I the coming future human race will open your tombs and cause you to come out of your tombs.
Jews are merely the people chosen by G'd to instruct that the human race is the chosen race.
If you read Psalm 8 verses 4 or 5 (Jewish verse enum is different), uncontaminated by doctrinal predilection - in its plain simple Hebrew: it says that G'd causes us humankind to be nearly G'd, just a little lesser. But people who cannot accept that, brazenly mistranslated the passage to say we are lesser than angels. Unbelievably brazen.
The human race is meant to play-god. G'd wants the human race to be His equal. G'd does not want to give us eternal life. G'd wants us to develop the capability/technology to have eternal life.
C'mon people, read Hosea 2:16 in the Hebrew: You shall call Me my-husband-peer, and no longer call Me my-husband-master.
G'd is waiting for His reciprocal, like an encryption Identity awaits the matching reciprocation signal. His bride. Are you the kind of men (or women) who believes that a wife should be inferior, submissive and fearful towards her husband? IF you are, then you are the type of people who wish to deprive G'd of a partner who is His equal.
