This is the meaning of the word sons in Genesis 6:2:-
H1121
בּן
bên
bane
From H1129; a son (as a builder of the family name), in the widest sense (of literal and figurative relationship, including grandson, subject, nation, quality or condition, etc., (like H1, H251, etc.): - + afflicted, age, [Ahoh-] [Ammon-] [Hachmon-] [Lev-]ite, [anoint-]ed one, appointed to, (+) arrow, [Assyr-] [Babylon-] [Egypt-] [Grec-]ian, one born, bough, branch, breed, + (young) bullock, + (young) calf, X came up in, child, colt, X common, X corn, daughter, X of first, + firstborn, foal, + very fruitful, + postage, X in, + kid, + lamb, (+) man, meet, + mighty, + nephew, old, (+) people, + rebel, + robber, X servant born, X soldier, son, + spark, + steward, + stranger, X surely, them of, + tumultuous one, + valiant[-est], whelp, worthy, young (one), youth.
It is not translated as angel
We have to go at this logically and apologetically: of course the word sons just means sons, nobody is countering that. But it's not just one word here, it's a whole different meaning of what kind of sons are we talking about. You have to look at the whole term - sons of God (OT), meaning here directly created by God not through women, in the NT it also means born of God or born again believers.
If you put another term there, e.g. son of the devil (as in Acts 10:13), you have a spiritual connotation which does not directly refer to anything created in the natural but spiritual in this case, even though it might refer to a person in which this spiritual relationship is created.
BTW you quoted the wrong Strongs number there, which means building up or to built, to make -not sons
This is the actual reference:
Strong's H1121 - ben
בֵּן
Transliteration = ben
1) son, grandson, child, member of a group
a) son, male child
b) grandson
c) children (pl. - male and female)
d) youth, young men (pl.)
e) young (of animals)
f) sons (as characterisation, i.e. sons of injustice [for un- righteous men] or
sons of God [for angels]
g) people (of a nation) (pl.)
h) of lifeless things, i.e. sparks, stars, arrows (fig.)
i) a member of a guild, order, class
There you see, it's proof in the original meaning of the texts as well as the ones I gave you before from Job where CLEARLY a scene in heaven is mentioned, where the sons of God come together, as other Bible translations also point out using "the angels" there. This is correct proof, what more do you need? Unless you don't want to see it on purpose. Since you have not even answered these posts and scriptures I gave before, but keep arguing against this whole subject as if avoiding them.
