Book of Enoch
Chapter XLIII
And I saw other lightnings and the stars of heaven, and I saw how He called them all by their names and they hearkened unto Him.
And I saw how they are weighed in a righteous balance according to their proportions of light: (I saw) the width of their spaces and the day of their appearing, and how their revolution produces lightning: and (I saw) their revolution according to the number of the angels, and (how) they keep faith with each other.
