The following assaults of the great Satanic Enemy stand out prominently in the Bible:

reference: therain.org Abraham's wife Sarai was captured by Pharaoh in Egypt (thinking she was Abraham's sister) before Isaac was born (Genesis, Chapter 12) Abraham's wife Sarai was captured (taken) by Abimelech, king of Gerar (thinking she was Abraham's sister) before Isaac was born.  (Genesis, Chapter 20) The attempted destruction of the male line of Israel in Egypt, Exodus 1:15-16:  15. And the king of Egypt spake to the Hebrew midwives, of which the name of one was Shiphrah, and the name of the other Puah: 16. And he said, When ye do the office of a midwife to the Hebrew women, and see them upon the stools; if it be a son, then ye shall kill him: but if it be a daughter, then she shall live. The destruction of the whole nation in Pharaoh's pursuit, Exodus 14. After David's line was singled out (2 Samuel 7), that was the next selected for assault. Satan's first assault was in the union of Jehoram and Athaliah by Jehoshaphat, notwithstanding 2 Chronicles 17:1. Jehoram killed off all his brothers (2 Chronicles 21:4). The Arabians slew all his children, except Ahaziah (2 Chronicles 21:17; 22:1). When Ahaziah died, Athaliah killed "all the seed royal" (2 Chronicles 22:10). The babe Joash alone was rescued; and, for six years, the faithfulness of Jehovah's word was at stake (2 Chronicles 23:3). Hezekiah was childless, when a double assault was made by the King of Assyria and the King of Terrors (Isaiah 36:1; 38:1). God's faithfulness was appealed to and relied on (Psalm 136). In Captivity, Haman was used to attempt the destruction of the whole nation (Esther 3:6,12,13. Compare 6:1). Joseph's fear was worked on (Matthew 1:18-20). Notwithstanding the fact that he was "a just man", and kept the Law, he did not wish to have Mary stoned to death (Deuteronomy 24:1); hence Joseph determined to divorce her. But God intervened: "Fear not". Herod sought the young Child's life (Matthew 2). At the Temptation, "Cast Thyself down" was Satan's temptation. At Nazareth, again (Luke 4), there was another attempt to cast Him down and destroy Him.    The two storms on the Lake were other attempts. At length the cross was reached, and the sepulchre closed; the watch set; and the stone sealed. But "God raised Him from the dead." And now, like another Joash, He is seated and expecting (Hebrews 10:12,13), hidden in the house of God on high; and the members of "the one body" are hidden there "in Him" (Colossians 3:1-3), like another Jehoshaba; and going forth to witness of His coming, like another Jehoiada (2Chronicles 23:3).    The irruption of "the fallen angels" ("sons of God") was the first attempt; and was directed against the whole human race.    When Abraham was called, then he and his seed were attacked.    When David was enthroned, then the royal line was assailed.    And when "the Seed of the woman" Himself came, then the storm burst upon Him.         “As many as are led by the Spirit of God, they are the sons of God.” —Romans viii. 14. Hildegard of Bingen wrote about fallen angels in 1150 AD.  She states they aligned themselves to the dark (negative) instead of to the light (positive-God per the Bible).

Another non-canonical tradition says that God's Angels swarmed down and killed the remaining Nephilim... God seeing his creation on the brink of destruction acted to save man from this treachery, and he set out to wipe corrupt man (and beast) from the face of the earth. God did not do this so as to punish man but to save him from an evil he had no way of understanding. God saved Noah and his family and man began anew.  As did the evil. But it was the unauthorized act of revelation that outraged the archangels, and it was that act which God punished. "I shall restore the Earth, so that not all the sons of men shall be destroyed through the mystery which the Watchers made known." Divinely commanded, the obedient Watchers swept down and defeated their brothers, whose punishment was to watch the death of their children before being themselves imprisoned in the mountains and deserts of the Earth until Judgment Day, when they will be cast into the lake of eternal fire. (Azazel is the only Watcher whose burial place is believed to be known: under a heap of stones at the foot of the cliff of Haradan, in what is now the Sinai, where, regarded as a demon, he received every year the scapegoat driven into the desert with its burden of Israel's sins. --Alternately, he is sometimes said to have hurled himself into the sky and become the constellation Orion.) God sends the prophet Enoch to scold them in their imprisonment, saying that as spiritual beings they were never intended to have wives as mortal men do (of course, their creator could presumably have seen to it that they felt no longing for sex or love, but he apparently neglected to do so) and even scorning the knowledge they shared with humanity - "You were in heaven, but its secret had not been revealed to you and a worthless mystery you knew." - although the Four Archangels' concern surely contradicts this mocking remark. Other Apocryphal books say that even now they are held and tortured in the terrible Fifth Heaven, set aside for just this purpose. (I Enoch XIII describes the Watchers/Grigori as stricken mute with guilt and terror after Enoch's reproof, and indeed in II Enoch the Grigori imprisoned in the Fifth Heaven are voiceless giants.) The world, meanwhile, is swept clean in a great earthquake and flood, destroying the Nephilim's lands, to which many writers trace the worldwide legends of a catastrophic inundation. But the Watchers' teaching continued to influence humankind in the ages after the Deluge, even though now condemned and studied in secret. In Jubilees VIII:1-5, Kainam, Noah's grandson, "came upon a writing which men of old had carved on a rock...it contained the teaching of the Watchers, in accordance with which they used to observe the omens of the sun and moon and all the signs of heaven. And he wrote it down and said nothing about it..." fearing punishment from Noah, who blamed the Watchers for the Flood and constantly warned his clan against any dealings with them or their descent. (Must have been one blessed huge rock, unless the Watchers' skills included micro-engraving.) This is especially notable because Kainam is the brother of Chesed, father of Ur, who is said in the Apocrypha to have founded the famous Chaldean city of that name. "And [they] grew up and lived in Ur of the Chaldees," says Jubilees (XI:7-8) of Serug and Nahor, Kainam's descendants, "and worshipped idols...and [Nahor's] father instructed him in the learning of the Chaldees, how to divine and foretell the future from the signs of heaven." It's most tempting to conclude that Kainam's grandchildren through generations inherited and studied the written record he had made from the stone; that the legendary wisdom of the Chaldeans, which amazes history, had descended to them from the Watchers themselves The Nephilim - and, some say, their children, the Elioud/Eljo - were physically exterminated by the avenging angel horde. But, though their half-mortal bodies could be slain, their half-angel souls could not, nor could they be held in chains. They remain on the earth, wandering at will, and though chaotic and destructive will not be punished for their deeds until the Final Judgment "in which the great age will be brought to an end". Occult tradition holds that now and then a Nephilim spirit will incarnate in human form (the souls of those who quit the body violently, it's said, are most pure...). The Apocrypha claim the disembodied Nephilim are the origin of demons, and accuse them of many crimes. Jubilees places the blame for the Flood squarely upon the fornication of the Watchers and the iniquity and bloodshed of the Nephilim. "And now the giants who were born from souls and flesh will be called evil spirits upon the earth," charges I Enoch XV-XVI, "From the day of...the slaughter and destruction of the giant Nephilim, the mighty ones of the earth, the great famous ones, the spirits that have gone out from their souls as from the flesh will destroy without judgment." Even the mortal women who are their mothers are cursed to become sirens and demonesses. In Jubilees X:1-6, Noah's sons beg him to protect their children from "unclean demons" who are "leading astray, blinding and killing" them; Noah, petitioning God to "let not wicked spirits rule over [my grandchildren] and destroy them", adds, "Thou knowest what thy Watchers, the fathers of these spirits, did in my day..." making it clear that the demonic spirits and the Nephilim are considered one and the same. (One wonders if Kainam was one of these grandchildren being "led astray" by a "demonic" Nephilim familiar. Maybe it was helping him interpret the stone...)

Archeology News
November 2005 Archaeologists digging at the purported biblical home of Goliath have unearthed a shard of pottery bearing an inscription of the Philistine's name, a find they claim lends historical credence to the Bible's tale of David's battle with Goliath.

While the discovery is not definitive evidence of Goliath's existence, it does support the Bible's depiction of life at the time the battle was supposed to have occurred, said Dr. Aren Maeir, a professor at Bar-Ilan University and director of the excavation.

"What this means is that at the time there were people there named Goliath," he said. "It shows us that David and Goliath's story reflects the cultural reality of the time."

Some scholars assert the story of David slaying the giant Goliath is a myth written down hundreds of years later. Maeir said finding the scraps lends historical credence to the biblical story.

The shard dates back to around 950 B.C., within 70 years of when biblical chronology asserts David squared off against Goliath, making it the oldest Philistine inscription ever found, the archaeologists said.

Scientists made the discovery at Tel es-Safi, a dig site in southern Israel thought to be to be the location of the Philistine city of Gath.

Maeir doubts an archaeological find can ever prove Goliath's existence, but said the shard was exciting nonetheless because of its depiction of life during the time period.
