Whiter than snow
“Behold, thou desireth truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow,”
Perfecting Holiness
“Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.”
