Isaiah 30:26
24 The oxen and donkeys used in plowing will eat seasoned feed winnowed with a shovel and pitchfork. 25 On every high mountain and every high hill there will be streams flowing with water, at the time of great slaughter when the fortified towers collapse. 26 The light of the full moon will be like the sun’s glare, and the sun’s glare will be seven times brighter, like the light of seven days, when the Lord binds up his people’s fractured bones and heals their severe wound. 27 Look, the name of the Lord comes from a distant place in raging anger and awesome splendor. He speaks angrily, and his word is like destructive fire.
2 Enoch 66:8
Secrets of Enoch7 Walk, my children, in long-suffering, in meekness, honesty, in provocation, in grief, in faith and in truth, in (reliance on) promises, in illness, in abuse, in wounds, in temptation, in nakedness, in privation, loving one another, till you go out from this age of ills, that you become inheritors of endless time. 8 Blessed are the just who shall escape the great judgment, for they shall shine forth more than the sun sevenfold, for in this world the seventh part is taken off from all, light, darkness, food, enjoyment, sorrow, paradise, torture, fire, frost, and other things; he put all down in writing, that you might read and understand.
Notes and References
"... As the reference is in the present to either the light of creation or the eschatological light, it implies a mystical notion. Moreover, the co-text contains esoteric descriptions of illumination and hence the expectation of sevenfold shining does not need to be merely metaphorical. Indisputably eschatological is the co-text of 1 Enoch 91:16 ... That these 'powers' may include the righteous is, I believe, confirmed by the longer recension of 2 Enoch 66:7 ..."
