Revelation 1:14

Verse Revelation 1:14. His head and his hairs were white like wool] This was not only an emblem of his antiquity, but it was the evidence of his glory; for the whiteness or splendour of his head and hair doubtless proceeded from the rays of light and glory which encircled his head, and darted from it in all directions. The splendour around the head was termed by the Romans nimbus, and by us a glory; and was represented round the heads of gods, deified persons, and saints. It is used in the same way through almost all the nations of the earth.

His eyes were as a flame of fire] To denote his omniscience, and the all-penetrating nature of the Divine knowledge.
