Genesis 6:11
10 Noah had three sons: Shem, Ham, and Japheth. 11 The earth was ruined in the sight of God; the earth was filled with violence. 12 God saw the earth, and indeed it was ruined, for all living creatures on the earth were sinful. 13 So God said to Noah, “I have decided that all living creatures must die, for the earth is filled with violence because of them. Now I am about to destroy them and the earth. 14 Make for yourself an ark of cypress wood. Make rooms in the ark, and cover it with pitch inside and out.
1 Enoch 9:1
1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed on the earth, and all lawlessness being committed on the earth. 2 And they said to one another: 'The earth, left without inhabitants, cries out, and the voice of their crying reaches the gates of heaven.' 3 'And now to you, the holy ones of heaven, the souls of men plead, saying, "Present our case before the Most High."'
Notes and References
"... In the introductory words to the Apocalypse, Enoch comforts the elect by telling them: “Let not your spirit be troubled because of the times; for the Great Holy One has appointed days for everything” (1 Enoch 92:1). These “times” are described in detail in the body of the Apocalypse. The parallelism between the Flood and the eschaton is evoked early in the text ... The phrase “the first end” assumes a second end later in the text. The words “deceit and violence” are significant here. “Violence” is the word used to signify the evil preceding the Flood in Genesis 6:11 and 6:13, 71 and in 1 Enoch 9:1. Both “deceit” and “violence” then reoccur in the seventh week, tying the weeks together ... The point seems clear enough: The chosen of these last days of perversity (1 Enoch 93:9) need not be alarmed - this has all happened before, as was foretold. In the same way, it was also foretold that this present evil will be judged even more decisively then in the days of Noah. In fact, the chosen will be part of that judgment ..."
