Nails of the fingers
In Deuteronomy 21:12, to pare the nails signifies to purify external falsities or that natural truth purified from falsities is adopted by good. (Arcana Coelestia 3703[16])
In Daniel 4:33, this signifies to become very sensuous. (Arcana Coelestia 1029[6])
Daniel 4:33
33
The same hour was the thing fulfilled on Nebuchadnezzar: and he was driven from men, and ate grass as oxen, and his body was wet with the dew of the sky, until his hair was grown like eagles' [feathers], and his nails like birds' [claws].
