2 Enoch

And the Cherubim and seraphim standing about the throne, the six-winged and many-eyed ones do not depart, standing before the Lord �s face doing his will, and cover his whole throne, singing with gentle voice before the Lord �s face: Holy, holy, holy, Lord Ruler of Sabaoth , heavens and earth are full of Your glory.

When I saw all these things, those men said to me: Enoch , thus far is it commanded us to journey with you, and those men went away from me and thereupon I saw them not.
