1 Enoch 9:4
3 'And now to you, the holy ones of heaven, the souls of men plead, saying, "Present our case before the Most High."' 4 And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, and God of the ages, the throne of Your glory stands through all generations, and Your name is holy and glorious and blessed through all ages! 5 You have created all things, and over all things, You have power: all things are open and visible in Your sight, and You see all things, and nothing can hide from You.
Sirach 36:22
Ben Sira, Ecclesiasticus20 Bear witness to those whom you created in the beginning, and fulfill the prophecies spoken in your name. 21 Reward those who wait for you and let your prophets be found trustworthy. 22 Hear, O Lord, the prayer of your servants, according to your goodwill toward your people, and all who are on the earth will know that you are the Lord, the God of the ages. 23 The stomach will take any food, yet one food is better than another. 24 As the palate tastes the kinds of game, so an intelligent mind detects false words.
Notes and References
"... The final title, “God of the ages” (θεὸς τῶν αἰώνων), occurs also in Sirach 36:22 in a prayer and is paralleled by the title “the God of eternity” (see 1 Enoch 1:4) and the formula “the God who lives forever” (1 Enoch 5:2). It forms a transition to the second and third lines of the strophe, which emphasize God’s eternity. The superlative “generation of the generations” and the double occurrence of “all/every” stress the totality of the conception ..."
