1 Enoch 7:6

1 And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms and enchantments, and the cutting of roots, and made them acquainted with plants. 2 And they became pregnant, and they bare great giants, whose height was three thousand ells: 3 Who consumed all the acquisitions of men. And when men could no longer sustain them, 4 the giants turned against them and devoured mankind. 5 And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood. 6 Then the earth laid accusation against the lawless ones.

New Testament

2 Thessalonians 2:8

6 And so you know what holds him back, so that he will be revealed in his own time. 7 For the hidden power of lawlessness is already at work. However, the one who holds him back will do so until he is taken out of the way, 8 and then the lawless one will be revealed, whom the Lord will destroy by the breath of his mouth and wipe out by the manifestation of his arrival. 9 The arrival of the lawless one will be by Satan’s working with all kinds of miracles and signs and false wonders, 10 and with every kind of evil deception directed against those who are perishing, because they found no place in their hearts for the truth so as to be saved.
