Daniel 10:6
5 I looked up and saw a man clothed in linen; around his waist was a belt made of gold from Ufaz. 6 His body resembled yellow jasper, and his face had an appearance like lightning. His eyes were like blazing torches; his arms and feet had the gleam of polished bronze. His voice thundered forth like the sound of a large crowd. 7 Only I, Daniel, saw the vision; the men who were with me did not see it. On the contrary, they were overcome with fright and ran away to hide.
2 Enoch 1:6
Secrets of Enoch4 On the first day of the month, I was alone in my house, resting on my bed, and fell asleep. 5 While asleep, great distress filled my heart, and I wept, unable to understand the cause of this distress or what would happen to me. 6 Two large men appeared to me, unlike any I had ever seen on earth; their faces shone like the sun, their eyes like burning lights, and fire came from their lips, along with clothing and songs of various kinds in purple appearance; their wings were brighter than gold, their hands whiter than snow.
Notes and References
"... Allison argues that ancient Jewish writers thought of the eye as functioning in the same way as the sun; thus, just as heavenly sources of light could become dimmed, so also the light of the eyes could be darkened. He maintains that they 'presuppose that the normal eye produces a subtle ray or light'. The difficulty with these examples is that many can be read in purely figrative or metaphorical terms. Against this potential objection, Allison posits a number of later noncanonical texts where the extramission theory is more plausible (e.g., 1 Enoch 106:2, 11). (Allison also compares this to the motif of fire coming forth from human and divine eyes, such as 2 Enoch 1:5; Daniel 10:6; Revelation 1:14, 2:18, 19:12; 3 Enoch 9:4; 18:25; 25:2-3. We should be careful in our dealings with passages describing the eyes of divine beings, particularly those in heavenly locations. Allison argues that these passages indicate that 'the normal eye produces a subtle ray or light, and that under the right circumstances or with exceptional individuals or supernatural beings such as angels, this light or ray can become intense and visible, even destructive') ..."
