Adam Clarke's Commentary on the Bible

Verse 14 (Jude 1:14)

Enoch also, the seventh from Adam - He was the seventh patriarch, and is distinguished thus from Enoch, son of Cain, who was but the third from Adam; this appears plainly from the genealogy, 1 Chronicles 1:1 ; : Adams Seth, Enosh, Kenan, Mahalaleel, Jered, Henoch or Enoch, etc. Of the book of Enoch, from which this prophecy is thought to have been taken, much has been said; but as the work is apocryphal, and of no authority, I shall not burden my page with extracts. See the preface.

Perhaps the word προεφητευσε , prophesied, means no more than preached, spoke, made declarations, etc., concerning these things and persons; for doubtless he reproved the ungodliness of his own times. It is certain that a book of Enoch was known in the earliest ages of the primitive Church, and is quoted by Origen and Tertullian; and is mentioned by St. Jerome in the Apostolical Constitutions, by Nicephorus, Athanasius, and probably by St. Augustine. See Suicer's Thesaurus, vol. i., col. 1131. Such a work is still extant among the Abyssinians.

Ten thousand of his saints - This seems to be taken from Daniel 7:10 .
