1 Enoch 87:1-4
Enoch witnesses animals attacking each other as earth cries out, then three white heavenly beings lift him to a high tower to observe coming judgments...
1And again I saw them, and they began to strike one another, and one devoured another, and the earth began to cry out.
2And I lifted up my eyes again toward heaven, and I saw in a vision, and behold, there came forth from heaven beings like the appearance of white men; and one came forth from that place and three with him.
3And those three who came forth last took hold of me by my hand and raised me up from the generations of the earth, and lifted me up to a lofty place, and showed me a tower high above the earth, and every hill was lower than it.
4And they said to me: 'Remain here until you see all that comes upon these elephants and camels and asses, and upon the stars and upon all the cattle.'
