This part might explain a lot of it between the scattering in 70AD all the way to today. Acts:10 was when God made all Gentile food clean as the last act for Jews alone before the scattering. Saul and the Jews are symbolic of the Jews that were not gathered at that time. God has a mission for the gathered also before all are gathered. The first case of persecution was in Portugal and the food part was probably a good deal of the 'forced conversion' as the 'State' became unwilling to cater to Jews having OT Kosher food only while the locals were starving. The exile from England in 1290 was over money so the money changers were in control by then. 1600 seems to be when the next big change took place.
Where did they come from in the first place is recorded in the Bible and the starting point was in 4,000BC +- 4 years.
And I will put enmity between thee and the woman,
and between thy seed and her seed;
it shall bruise thy head,
and thou shalt bruise his heel.
And there appeared a great wonder in heaven;
a woman clothed with the sun,
and the moon under her feet,
and upon her head a crown of twelve stars:
And she being with child cried,
travailing in birth,
and pained to be delivered.
And she brought forth a man child,
who was to rule all nations with a rod of iron:
and her child was caught up unto God,
and to his throne.
Noah and his family were the last 5 fingered people alive when the flood was determined, if they had been killed Jesus could not have been born and the cross would not have been the fulfillment. God sent Christ so there would be no balking like Jonah did. The details of the other bruise is in prophecy only, there is a lot of it so imagination is not needed, a lot of reading is though.
This summation will not do justice to the 'long version'.
When God does something special for a person he demands a payment. Moses felt inner pride so God punished him by keeping him out of the promised land until he was in a vision with Elias and Christ. He will be at that spot again on the day He returns and all 7 vials kill all sinners in the world in a few hours and then in the few hours that follow that all the resurrections in Eze:37 take place. That is when they are brought home by God.
And lest I should be exalted above measure through the abundance of the revelations,
there was given to me a thorn in the flesh,
the messenger of Satan to buffet me,
lest I should be exalted above measure.
For this thing I besought the Lord thrice,
that it might depart from me.
And he said unto me,
My grace is sufficient for thee:
for my strength is made perfect in weakness.
Most gladly therefore will I rather glory in my infirmities,
that the power of Christ may rest upon me.
Therefore I take pleasure in infirmities,
in distresses for Christ's sake:
for when I am weak,
then am I strong.
The first step in Mary being the mother of Jesus was Abraham being given a blessing that sealed him from harm so he would become the rather of the man that is the cornerstone of the 12 Tribes. The drama around that and all the way to the birth of Jesus is in such detail to show it is historical rather than mythical.
(Much is required such as being sold into slavery and then your whole family shows up like they are out of the movie Vacation for a short stay of 430 years and then leave without paying the bill.)
The timing and the extermination of the Giants is important but not to this aspect of the book. We are between the scattering in 70AD in Luke:21:24 which is a fulfillment of the scattering part of the De:4:30 prophecy. The 'latter' days starts with the 1st trump sounding, 4 days later Satan shows up with 1 of the fallen angels that was a 'son of God' when the 5th trump sounds. For the next 3 1/2 years it is like the days of Noah and the program is the same. exterminate all 5 fingered people.
And the LORD shall scatter thee among all people,
from the one end of the earth even unto the other;
and there thou shalt serve other gods,
which neither thou nor thy fathers have known,
even wood and stone.
That then the LORD thy God will turn thy captivity,
and have compassion upon thee,
and will return and gather thee from all the nations,
whither the LORD thy God hath scattered thee.
The 144,000 are sealed before the 1st trump sounds and the rest of the whole of the 12 Tribes joins them as the last event on the day the two witnesses are resurrected.
Like the OT they never got to reap the rewards of being 'His people'. The wars that ended when they enter that place were replaced by civil wars so there was 'no rest'. The bruise to Satan's head takes place in Jerusalem, the Temple in the times of Jesus was needed for the completion of the bruise to the heel, without that all the ones gathered in the NT could have been gathered like Daniel was and that could have turned into the 70AD scattering as well.
God's version picks up when the 1st trump sounds, the details are pretty clear and today it is promoted by some people with 'clear heads' that Damascus should be nuked based on a single verse. I have a ready reply for that.
God also made a stumbling block for the Jews by John the Baptist being called like Moses was by the message was recorded by a Disciple of his in Greek when none of them were ever taught Greek.
Sometimes slick is better than 'all powerful'.
Ezekiel:38 and the Gog war. Ezekiel:38 is for the 1,000 year reign and the 'battle' that comes when Satan and all remaining fallen angels in the Pit are released and joined by the ones whose bones are buried in a graveyard in Israel in Ezekiel:39.
The people that are there at the end of the chapter are the ones at the start of the chapter that complete the 7 year clean-up and the 7 months of gathering some bones and burying them in a special graveyard that has the name Gog attached to it. The bones belong to the 4 fallen angels that manifest into the 200M horsemen and it is by these being that the 12 Tribes are brought down to being just the 144,000. By the evening of the day Jesus returns and kills all sinners the whole House of Israel will be alive and standing in Israel.
If Gog does not exist until 7 years into the 1,000 year reign then they cannot be in a war at the start because part of the vials is the river of blood and that is the death of those angelic horsemen. There are a few clues in Eze:38 that it is the 1,000 years such as Jerusalem is an unwalled city during that time and it is only during that time that the people are living in safety for the first time. An earlier reference to Damascus being part of prophecy that you believe is happening either means you are working off materials somebody has handed you or you missed more than a passage or two of Scripture. The bones of men that dies as part of the return do not have their bones gathered and placed in the City of Gog.
Damascus is 1 Gentile city mentioned when all Gentile cities are also flattened. Jerusalem is the first one and it is hit with the same fire that God used on Sodom.
And the seventh angel poured out his vial into the air;
and there came a great voice out of the temple of heaven,
from the throne,
It is done.
And there were voices,
and there was a great earthquake,
such as was not since men were upon the earth,
so mighty an earthquake,
and so great.
And the great city was divided into three parts,
and the cities of the nations fell:
and great Babylon came in remembrance before God,
to give unto her the cup of the wine of the fierceness of his wrath.
And every island fled away,
and the mountains were not found.
And there fell upon men a great hail out of heaven,
every stone about the weight of a talent:
and men blasphemed God because of the plague of the hail;
for the plague thereof was exceeding great.
and the cities of Judah,
and the kings thereof,
and the princes thereof,
to make them a desolation,
and a curse;
as it is this day;
And all the kings of the north,
far and near,
one with another,
and all the kingdoms of the world,
which are upon the face of the earth:
and the king of Sheshach shall drink after them.
I begin to bring evil on the city which is called by my name,
and should ye be utterly unpunished?
Ye shall not be unpunished:
for I will call for a sword upon all the inhabitants of the earth,
saith the LORD of hosts.
Thus saith the LORD of hosts,
evil shall go forth from nation to nation,
and a great whirlwind shall be raised up from the coasts of the earth.
And the slain of the LORD shall be at that day from one end of the earth even unto the other end of the earth:
they shall not be lamented,
they shall be dung upon the ground.
For I will gather all nations against Jerusalem to battle;
and the city shall be taken,
and the houses rifled,
and the women ravished;
and half of the city shall go forth into captivity,
and the residue of the people shall not be cut off from the city.
Then shall the LORD go forth,
and fight against those nations,
as when he fought in the day of battle.
When the Son of man shall come in his glory,
and all the holy angels with him,
then shall he sit upon the throne of his glory:
And before him shall be gathered all nations:
and he shall separate them one from another,
as a shepherd divideth his sheep from the goats:
All nations means all nations.
