Then they that were in the ship came and worshipped him, saying: Of a truth you are the Son of Elohiym.
Mattithyahu (Matthew) 14:33

Here is this phrase we see the use of the Greek terms θεου υιος (Theos uios). The practice of the את Cepher is consistent with the Septuagint in translating the Ivriyt term (אֱלֹהִים) Elohiym as (θεου) as Theos and vice-versa.  As a consequence, we see the very explosive phrasing in the Besoroth setting forth the term of art beni Elohiym (בְּנֵי הָאֱלֹהִים).

In the Tanakh, we see this phrase only four times: Bere’shiyth (Genesis) 6:2; 6:4; and Iyov (Job) 1:6; 2:1.

Before we look closely at those verses, consider the following:

I have said: Ye are elohiym; and all of you are children of El Elyon. 7 But ye shall die like men and fall like one of the princes. 8 Arise, O Elohiym, judge the earth: for you shall inherit all nations.
Tehilliym (Psalms) 82:6-7

We are going to see several things here, but they are distinguishable as particularized phrases or terms of arts.

Let us first examine the Ben’i Elohiym:

And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, 2 That the sons of Elohiym saw the daughters of men that they were fair; and they took them women of all which they chose.7 3 And Yahuah said, My Ruach shall not always strive with man, for that he also is flesh: yet his days shall be a hundred and twenty years. 4 There were Naphaliym in the earth in those days, who also gathered afterward, when the sons of Elohiym came in unto the daughters of A’dam, and they bore children unto them, the same were warriors and tyrants which were from time out of mind, mortal men of renown.
Bere’shiyth (Genesis) 6:1-4

Those who committed the great error were the sons of Elohiym – the ben’i Elohiym. So who are they and what are they about?

Iyov (Job) will tell us more specifically concerning their capability:

Now there was a day when the sons of Elohiym came to present themselves before Yahuah, and Satan came also among them. 7 And Yahuah said unto Satan: From whence come you? Then Satan answered Yahuah and said: From going to and fro in the earth, and from walking up and down in it.
Iyov (Job) 1:6-7

Again there was a day when the sons of Elohiym came to present themselves before Yahuah, and Satan came also among them to present himself before Yahuah. 2 And Yahuah said unto Satan: From whence come you? And Satan answered Yahuah and said: From going to and fro in the earth, and from walking up and down in it.
Iyov (Job) 2:1

It is of some relevance here that we see the ben’i Elohiym traveling with the adversary (Ha’Satan) with specific capability. First, they are found presenting themselves before Yahuah in heaven. This is a capability not found in mankind (A’dam) following the fall (but was likely present prior to the fall).

Second, the beni Elohiym had the capability to go to and from the earth, and to walk up and down on it. Once again, we see a capacity not found in A’dam, but found in the beni Elohiym. So who were they? Did they exist prior to the creation of A’dam? It appears so.

And Elohiym said: Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creeps upon the earth. 27 So Elohiym created man in his own image, in the image of Elohiym created he him; male and female created he them. 28 And Elohiym blessed them, and Elohiym said unto them: Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moves upon the earth.
Bere’shiyth (Genesis) 1:26-28

If Elohiym (as compared to Yahuah Elohiym who would create A’dam) created mankind (“let us make man in our image”), then those created would be called the beni Elohiym – the sons of Elohiym. Are they distinct from A’dam? They may be, as A’dam and Chuah are called respectively Ish (man) and Ishah (woman), while those created in Chapter One are called zakar (male) and neqabah (female).

There is no debate among the academicians that the angels were created before man. But when we talk about angels, the word referencing this class in the Ivriyt is actually malach, meaning messenger.

Mălʼâk (מֲלְאָךְ) H4397, from an unused root meaning to dispatch as a deputy; a messenger; specifically, of Elohiym, i.e. an angel (also a prophet, priest or teacher): an ambassador, angel, king (melek), messenger.

So, are the messengers the beni Elohiym? If so, we can see that they were created male and female!

Now, let’s take a look at the term Watcher, which is found throughout Chanoch and to whom is assigned all the wickedness in the world.

ʻîyr (עִיר) H5894, from a root corresponding to H5782; a watcher, i.e. an angel (as guardian): a watcher.

ʻîyr (עִיר) H5892, or (in the plural) עָר ʻâr; or עָיַר ʻâyar; (Jg 10:4), from H5782 a city (a place guarded by waking or a watch) in the widest sense (even of a mere encampment or post):

ʻûwr (עוּר) H5782 is the primitive root (rather identical with through the idea of opening the eyes); to waken (literally or figuratively): — an wakened one, lift up (self), master, raise (up), stir up (self): - woke

ʻûwr (עוּר) H5783, a primitive root; to (be) bare: —be made naked.

Now consider the ultimate fate of the believer:

He came unto his own, and his own received him not. 12 But as many as received him, to them he gave power to become the sons of Elohiym, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of Elohiym.
Yochanon (John) 1:11-13

Behold, what manner of love the Father has bestowed upon us, that we should be called the sons of Elohiym [beni Elohiym): therefore the world knows us not, because it knew him not. 2 Beloved now are we the sons of Elohiym [beni Elohiym], and it does not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
Yochanon Ri’shon (1 John) 3:1-2

For as many as are led by the Ruach Elohiym, they are the sons of Elohiym. 15 For ye have not received the ruach of bondage again to fear; but ye have received the Ruach Aymots, whereby we cry: Abba, Father. 16 The Ruach itself bears witness with our ruach, that we are the children of Elohiym: 17 And if children, then heirs; heirs of Elohiym, and joint heirs with Mashiach; if so be it that we suffer with him, that we may be also glorified together.
Romayim (Romans) 8:14-17

However the claim of Yahusha was not of the beni Elohiym, but in the singular, the Ben Elohiym.

When Yahusha came into the coasts of Qeycaryah Philippi, he asked his Talmidiym, saying: Whom do men say that I the Son of A’dam am? 14 And they said: Some say that you are Yahuchanon the Baptizer: some, Eliyahu; and others, Yirmeyahu, or one of the prophets. 15 He said unto them: But who say ye that I am? 16 And Shim`on Kepha answered and said: You are Ha’Mashiach, the Son of the living Elohiym.
Mattithyahu (Matthew) 16:13-16
