1 Enoch 39:9
8 And I saw his dwelling-place under the wings of the Lord of Spirits. 9 And all the righteous and elect before Him shall be †strong† as fiery lights, And their mouth shall be full of blessing, And their lips extol the name of the Lord of Spirits, And righteousness before Him shall never fail, [And uprightness shall never fail before Him.] 10 There I wished to dwell, And my spirit longed for that dwelling-place: And there heretofore hath been my portion, For so has it been established concerning me before the Lord of Spirits. 11 In those days I praised and extolled the name of the Lord of Spirits with blessings and praises, because He hath destined me for blessing and glory according to the good pleasure of the Lord of Spirits. 12 For a long time my eyes regarded that place, and I blessed Him and praised Him, saying: 'Blessed is He, and may He be blessed from the beginning and for evermore.
Hebrews 12:9
6 For the Lord disciplines the one he loves and chastises every son he accepts.” 7 Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline? 8 But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons. 9 Besides, we have experienced discipline from our earthly fathers and we respected them; shall we not submit ourselves all the more to the Father of spirits and receive life? 10 For they disciplined us for a little while as seemed good to them, but he does so for our benefit, that we may share his holiness. 11 Now all discipline seems painful at the time, not joyful. But later it produces the fruit of peace and righteousness for those trained by it.
Notes and References
"... Angels serve God in different functions in Jewish literature: they are (a) angelic revealers or heavenly guides for those such as Enoch who visit heaven in apocalyptic visions; (b) they serve in a cultic capacity within the heavenly sanctuary, primarily praising God, but also “standing24 at his side and serving his will”; and they (c) serve as messengers or helpers of God to humanity. Early Jewish literature understood angels as mere “servants” of God. 1 Enoch speaks frequently of “the Lord of the Spirits” – which reminds strongly of the formulation in Hebrews 12:9: “Father of spirits” (τῷ πατρὶ τῶν πνευµάτων). Philo refers to ἄγγελοι λειτουργοί (Virt. 74) and so does the Testament of Levi (“there with him are the archangels, who serve and offer propitiatory sacrifices to the Lord,” Testament of Levi 3:5). In the quotation from Psalm 103:4 (LXX) in Hebrews 1:7, it is particularly the λειτουργοί who are made “flames of fire” – which should be understood in a cultic sense as the LXX versions use the term overwhelmingly in a cultic manner ..."
