“Now draw thy hand close to thy side: It shall come forth white (and shining), without harm (or stain),- as another Sign,-
The second of the greater Miracles shown to
Moses was the “White (shining) Hand”.
Ordinarily, when the skin becomes white, it is a sign of
disease, leprosy or something loathsome. Here there was
no question of disease: on the contrary, the hand was
glorified, and it shone as with a divine light.
Such a miracle was beyond Egyptian or human magic.
