Genesis 6:1-5 (KJV)
1And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
4 There were giants in the earth in those days; 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 mighty men which were of old, men of renown.
5 And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Numbers 13:23-24 (NIV)
23 When they reached the Valley of Eshkol, they cut off a branch bearing a single cluster of grapes. Two of them carried it on a pole between them, along with some pomegranates and figs. 24 That place was called the Valley of Eshkol because of the cluster of grapes the Israelites cut off there.
Numbers 13:30-33 (NIV)
30 Then Caleb silenced the people before Moses and said, “We should go up and take possession of the land, for we can certainly do it.”
31 But the men who had gone up with him said, “We can’t attack those people; they are stronger than we are.” 32 And they spread among the Israelites a bad report about the land they had explored. They said, “The land we explored devours those living in it. All the people we saw there are of great size. 33 We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.”

The Book of Enoch 15: 1-11
1.And He answered and said to me, and I heard His voice: 'Fear not,Enoch, thou righteous man and scribe of righteousness: approachhither and hear my voice. 2. And go, say to the Watchers of heaven,who have sent thee to intercede for them: "You shouldintercede" for men, and not men for you: 3. Wherefore have yeleft the high, holy, and eternal heaven, and lain with women, anddefiled yourselves with the daughters of men and taken to yourselveswives, and done like the children of earth, and begotten giants (asyour) sons? 4. And though ye were holy, spiritual, living the eternallife, you have defiled yourselves with the blood of women, and havebegotten (children) with the blood of flesh, and, as the children ofmen, have lusted after flesh and blood as those also do who die andperish. 5. Therefore have I given them wives also that they mightimpregnate them, and beget children by them, that thus nothing mightbe wanting to them on earth. 6. But you were formerly spiritual,living the eternal life, and immortal for all generations of theworld. 7. And therefore I have not appointed wives for you; for asfor the spiritual ones of the heaven, in heaven is their dwelling. 8.And now, the giants, who are produced from the spirits and flesh,shall be called evil spirits upon the earth, and on the earth shallbe their dwelling. 9. Evil spirits have proceeded from their bodies;because they are born from men, and from the holy Watchers is theirbeginning and primal origin; they shall be evil spirits on earth, andevil spirits shall they be called. 10. As for the spirits of heaven,in heaven shall be their dwelling, but as for the spirits of theearth which were born upon the earth, on the earth shall be theirdwelling. 11. And the spirits of the giants afflict, oppress,destroy, attack, do battle, and work destruction on the earth, andcause trouble: they take no food, but nevertheless hunger and thirst,and cause offenses. And these spirits shall rise up against the children of men andagainst the women, because they have proceeded from them.
