Snow
This is taken in scripture as a symbol of “whiteness.” The sins as scarlet become as white as snow; the raiment of the Lord in the transfiguration was as white as snow (Psa. 51:77Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow. (Psalm 51:7); Isa. 1:1818Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. (Isaiah 1:18); Lam. 4:77Her Nazarites were purer than snow, they were whiter than milk, they were more ruddy in body than rubies, their polishing was of sapphire: (Lamentations 4:7); Dan. 7:99I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire.
