1 Enoch 61:10
8 And the Lord of Spirits placed the Chosen One on the throne of glory, and he shall judge all the works of the holy above in heaven, and in the balance their deeds shall be weighed. 9 And when he lifts up his countenance to judge their secret ways according to the word of the Lord of Spirits, and their path according to the way of the righteous judgment of the Lord of Spirits, then they all shall speak and bless with one voice, and glorify, extol, and sanctify the name of the Lord of Spirits. 10 And He will summon all the hosts of the heavens, and all the holy ones above, and the host of God, the Cherubic, Seraphim, and Ophanim, and all the angels of power, and all the angels of principalities, and the Chosen One, and the other powers on the earth and over the water. 11 On that day, they shall raise one voice, and bless and glorify and exalt in the spirit of faith, wisdom, patience, mercy, judgment, peace, and goodness, and shall all say with one voice: 'Blessed is He, and may the name of the Lord of Spirits be blessed forever and ever.'
2 Thessalonians 1:7
5 This is evidence of God’s righteous judgment, to make you worthy of the kingdom of God, for which in fact you are suffering. 6 For it is right for God to repay with affliction those who afflict you, 7 and to you who are being afflicted to give rest together with us when the Lord Jesus is revealed from heaven with his mighty angels. 8 With flaming fire he will mete out punishment on those who do not know God and do not obey the gospel of our Lord Jesus. 9 They will undergo the penalty of eternal destruction, away from the presence of the Lord and from the glory of his strength, 10 when he comes to be glorified among his saints and admired on that day among all who have believed—and you did in fact believe our testimony.
Notes and References
"... As has already been noted, the context of 1 Enoch and the parallel text, Deuteronomy 33:2-4, where it is employed, is that of theophany. This fits in with the primary themes in Jude as these passages describing God's giving of the Law at Sinai and his theophany with the presence of “myriads of angels,’ reference “the very beings that Jude’s opponents ‘slander’ (verse 8) by their antinomian mindset.” It is also argued that not only Jude, but also other New Testament writers, in their eschatological doctrine, are influenced by the language of an attendant angelic company in their depiction of Christ's second coming. Thus the “holy ones” are identified with the holy angels, the heavenly army of the Divine warrior, as in Zechariah 14:5, which is likely the main background to the early Christian expectation that the Lord at his Parousia would be accompanied by a retinue of angels. (Compare with Matthew 16:27; 25:31; Mark 8:38; Luke 9:26; 2 Thessalonians 1:7) Jude’s use of the “holy ones” to refer to angels, as it is used in 1 Enoch, therefore, signifies both Jude's highly developed angelology and his strong dependence on and high regard for 1 Enoch ..."
