I'm not a bible expert but here's my take!
Using "Strong's Corcordance", let's us examine the kings and tribes from these verses in Genesis. I got a hint that the tribes here were nephilim tribes or a nephilim controlled tribes meaning its leadership and high ranking positions are accupied by them. Rest of the tribes were ordinary populate.
Genesis 14:1-7, "{1} And it came to pass in the days of Amraphel king of Shinar, Arioch king of Ellasar, Chedorlaomer king of Elam, and Tidal king of nations; {2} That these made war with Bera king of Sodom, and with Birsha king of Gomorrah, Shinab king of Admah, and Shemeber king of Zeboiim, and the king of Bela, which is Zoar. {3} All these were joined together in the vale of Siddim, which is the salt sea. {4} Twelve years they served Chedorlaomer, and in the thirteenth year they rebelled. {5} And in the fourteenth year came Chedorlaomer, and the kings that were with him, and smote the Rephaims in Ashteroth Karnaim, and the Zuzims in Ham, and the Emims in Shaveh Kiriathaim, {6} And the Horites in their mount Seir, unto Elparan, which is by the wilderness."
Here are the transliteration of words based on "Strong's Concordance" from English to Hebrew together with its meaning or definition:
1. Amraphel (am-raw-fel'), king of Shinar = "sayer of darkness: fall of the sayer"; From the book of Jasher, Amraphel equals Nemrod; From "Genesis 10 Brenton's Septuagint verses 8 and 9", "{8} Nebrod: he began to be a giant upon the earth. {9] He was a giant hunter before the Lord God; therefore they say, As Nebrod the giant hunter before the Lord."
2. Arioch (ar-yoke'), king of Ellasar = "lion-like"; the chief of the executioners for Nebuchadnezzar
3. Chedorlaomer (ked-or-law-o'-mer), king of Elam = "handful of sheaves"; the king of Elam defeated by Abraham.
4. Tidal (tid-awl'), king of Nation = "great son"; fearfulness; Tidal, a Canaanite
5. Bera (beh'-rah), king of Sodom = "son of evil"
6. Birsha (beer-shah'), king of Gomorrah = "with iniquity"; with wickedness
7. Rephaims (raw-faw') in Ashteroth Karnaim = giants, Rephaim; old tribe of giants
8. Zuzims (zoo-zeem') in Ham = "roving creatures"; an ancient people of uncertain origin
9. Emims (ay-meem') in Shaveh Kiriathaim = "terrors"; ancient inhabitants of Moab; they also were accounted giants, as the Anakims; but the Moabites call them Emims. Deuteronomy 2:9-12
10. Horites (kho-ree') in mount Seir = "cave dweller"; the inhabitants of Seir and later become Edom at the time of Esau
It only shows that these tribes were not ordinary and Abraham wasn't dealing with simple tribes but a group people with extraordinary power. But God was on the side of Abraham, that's why he defeated the leader of the kings, Chedorlaomer in a battle to rescue his nephew Lot. Therefore Abraham, Isaac and Jacob where not dealing with simple tribes around Canaan but a people group whose origin can be traced wayback before the flood. It wasn't explained how the nephilim survived the flood but the remnants are here with us today. And looking at the Gog of Magog at Ezekiel 38, the remnants stayed in the area of the sons of Japheth and to the countries they created. That's why their population were significant to these areas but not too many. And that's why we have two people group of today. You will know them through science!
Daniel was accurate in his prophecy in the last days. The world will be divided between "Iron" and "Clay". Who are the clay? Isaiah 64:8, "But now, O Lord, thou art our Father; we are the clay, and thou our potter; and we all are the work of thy hand", it points out that we are the clay which God has formed during creation." If ordinary men, we, are the "Clay"... then who are they, the "Iron"? It could only means they are the remnants of nephilim. Therefore, the kingdoms of Daniel's prophecy were controlled by nephilim bloodlines. The "Gold", "Silver", "Brass" and "Iron". Look at Daniel 2:43, "And whereas thou sawest the iron mixed with miry clay, they shall mingle themselves with the seed of men, but they shall not cleave one to another, even as iron doth not mingle with clay." What is this? They are trying to mingle with the seed of men? Therefore, there bloodline really exist! Where are they?
Actually, I don't want to disclose what I'd learned regarding them but I can't take it any longer. Crucial times are here with us and I feel the urgency to share it with you. But always remember, Messiah came to saved us all, yes all! Incuding them! Only if we have faith in Him and keep His commandment. Now, here's what I found! A quote coming from the remnant their bloodline: "Most people have no idea what their blood type is whether it RH negative or RH positive. It has to be one or the other... but what does RH means? RH stands for Rhesus monkey and you either test positive for Rhesus monkey gene or negative. You either got it or you don't. Only 15% of the population test negative of the monkey gene and they are of European descent. Decades ago, couples had their blood test for Rhesus monkey gene. An RH negative woman who mates with an RH positive man will abort the fetus without medical intervention." Tell me! Is Daniel accurate in his prophecy in chapter 2 verse 43? Absolutely! We see it fulfilled right before our eyes! And this things, the product of their mingling, only happened in the divided kingdom. Before the divided kingdom, the kingdom of iron (Rome) to kingdom of gold (Babylon) era, the mixing of bloodline can still produce a sibling... nagkakaanak pa sila. Elohim (God) really moves in mysterious way! This verse from Genesis further proved that they existed; Genesis 3:15, "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." 'Her seed' or 'Eve seed' is us, normal men and Messiah bruised the head of the serpent. 'Thy seed' or 'nephilim seed', the hybrids... RHn. Always put this in mind, this prophecy came directly from our Holy Elohim (God). These are His words, from the mouth the Most High! Therefore, we can see only all truth here, that this people group really existed!
This explains why the Israelites destroyed them all, the tribes, including women and children on their way to Canaan. Their bloodline was unredeemable back then and it was abomination to God before Messiah came. Their seed (the nephilim) came from the fallen angels who transgressed the law of God by mating with the daughters of men in Genesis chapter 6. And the plan of Salvation was designed to include them. This is the reason why one of the apostles was tasked to preach the gospel to the gentiles because he came from them.
Who are the remnant of them, the true enemy of Messiah that never accepted Him? It's the pharisees and sadducees! Most of them migrated to Europe after the temple was destroyed in 70 AD. They became a leading figures of Europeans monarchy, governments top brass and commercial elites. It was their bloodline who created religion, world government, commerce, education, etcetera. It also was their bloodline who created science to trick us, to lure us and it's very well accepted in our our society today. This same tool backfired to them coz this tool was used to identify them. Daniel is so precise in his prediction; Daniel 12:4, "But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased." Use your knowledge to study the bible. Ask for guidance and Messiah will be your light... He will shine even it dark places. Wisdom, understanding and knowledge will be poured out to you!
