9 And the great dragon was cast down, the old serpent, he that is called the Devil and Satan, the deceiver of the whole world; he was cast down to the earth, and his angels were cast down with him.
10 And I heard a great voice in heaven, saying, Now is come the salvation, and the power, and the kingdom of our God, and the authority of his Christ: for the accuser of our brethren is cast down, who accuseth them before our God day and night.

25. THE
NEPHILIM, OR "GIANTS"
Of GEN. 6, &c.
The progeny of the fallen angels with the daughters of Adam (see notes on Gen. 6, and
Ap. 23) are called in Gen. 6, Ne-phil-im, which means fallen ones (from naphal, to fall). What these beings were can be gathered only from Scripture. They were evidently great in size, as well as great in wickedness. They were superhuman, abnormal beings; and their destruction was necessary for the preservation of the human race, and for the faithfulness of Jehovah's Word (Gen. 3:15).
This was why the Flood was brought "upon the world of the ungodly" (2Pet. 2:5) as prophesied by Enoch (Jude 14).
But we read of the Nephilim again in Num. 13:33 : "there we saw the Nephilim, the sons of Anak, which come of the Nephilim". How, it may be asked, could this be, if they were all destroyed in the Flood? The answer is contained in Gen. 6:4, where we read : "There were Nephilim in the earth in those days (i.e. in the days of Noah); and also AFTER THAT, when the sons of God came in unto the daughters of men, and they bare children to them, the same became [the] mighty men (Heb. gibbor, the heroes) which were of old, men of renown" (lit. men of the name, i.e. who got a name and were renowned for their ungodliness).
So that "after that", i.e. after the Flood, there was a second irruption of these fallen angels, evidently smaller in number and more limited in area, for they were for the most part confined to Canaan, and were in fact known as "the nations of Canaan". It was for the destruction of these, that the sword of Israel was necessary, as the Flood had been before.
As to the date of this second irruption, it was evidently soon after it became known that the seed was to come through Abraham; for, when he came out from Haran (Gen. 12:6) and entered Canaan, the significant fact is stated : "The Canaanite was then (i.e. already) in the land." And in Gen. 14:5 they were already known as "Raphain" and Emim", and had established themselves at Asteroth Karnaim and Shaven Kiriathaim.
In ch. 15:18-21 they are enumerated and named among Canaanite Peoples : "Kenites, and the Kenizzites, and the Kadmonites, and the Hittites, and the Perizzites, and the Rephaims, and the Amorites, and the Girgashites, and the Jebusites" (Gen. 15:19-21; cp. Ex. 3:8, 17; 23:23. Deut. 7; 20:17. Josh. 12:8).
These were to be cut off, and driven out, and utterly destroyed (Deut. 20:17. Josh. 3:10). But Israel failed in this (Josh. 13:13; 15:63; 16:10; 17:18. Judg. 1:19, 20, 28, 29, 30-36; 2:1-5; 3:1-7); and we known not how many got away to other countries to escape the general destruction. If this were recognized it would go far to solve many problems connected with Anthropology.
As to their other names, they were called Anakim, from on Anak which came of the Nephilim (Num. 13:23), and Rephaim, from Rapha, another notable one among them. From Deut. 2:10, they were known by some as Emim, and Horim, and Zamzummim (v. 20, 21) and Avim, &c.
As Rephaim they were well known, and are often mentioned : but, unfortunately, instead of this, their proper name, being preserved, it is variously translated as "dead", "deceased", or "giants". TheseRephaim are to have no resurrection. This fact is stated in Isa. 26:14 (where the proper name is rendered "deceased," and v. 19, where it is rendered "the dead"). It is rendered "dead" seven times (Job 26:5. Ps. 88:10. Prov. 2:18; 9:18; 21:16. Isa. 14:8; 26:19). It is rendered "deceased" in Isa. 26:14.
It is retained as a proper name "Rephaim" ten times (two being in the margin). Gen. 14:5; 15:20. Josh. 12:15 (marg.). 2Sam. 5:18, 22; 23:13.& b31 nbsp; 1Chron. 11:15; 14:9; 20:4 (marg.). Isa. 17:5. In all other places it is rendered "giants", Gen. 6:4; Num. 23:33, where it is Nephilim; and Job 16:14, where it is gibbor (
Ap. 14. iv). By reading all these passages the Bible student may know all that can be known about these beings.
It is certain that the second irruption took place before Gen. 14, for there the Rephaim were mixed up with the five nations or peoples, which included Sodom and Gomorrha, and were defeated by the four kings under Chedorlaomer. Their principal locality was evidently "Ashtaroth Karnaim"; while the Emimwere in the plain of Kiriathaim (Gen. 14:5).
Anak was a noted descendant of the Nephilim; and Rapha was another, giving their names respectively to different clans. Anak's father was Arba, the original builder of Hebron (Gen. 35:27. Josh. 15:13; 21:11); and this Palestine branch of the Anakim was not called Arbahim after him, but Anakim after Anak. They were great, mighty, and tall (Deut. 2:10, 11, 21, 22, 23; 9:2), evidently inspiring the ten spies with great fear (Num. 13:33). Og king of Bashan is described in Deut. 3:11.
Their strength is seen in "the giant cities of Bashan" to-day; and we know not how far they may have been utilized by Egypt in the construction of buildings, which is still an unsolved problem. Arba was rebuilt by the Khabiri or confederates seven years before Zoan was built by the Egyptian Pharoahs of the nineteenth dynasty. See note on Num. 13:22.
If these Nephilim, and their branch of Rephaim, were associated with Egypt, we have an explanation of the problem which has for ages perplexed all engineers, as to how those huge stones and monuments were brought together. Why not in Egypt as well as in "the giant cities of Bashan" which exist, as such, to this day?

Some giants , some men of renown .. You need to learn to distinguish between Jewish fables and the truth God is you want to continue on . You can use outside sources to aid the Word of God but you can't to change it .. You are content with your belief and you will be on the wrong road drawing further away imo if you're not grounded in the Word and I know you agree .. One final, If fallen angels could mate with women it would still be going on today unless you think they operate on an honor code ..I've addressed just about everything including in this thread including the Coral Castle reference to impossible ancient building ..
