PLAGUE OF DARKNESS. (Exo 10:21-29) Stretch out thine hand toward heaven, that there may be darkness--Whatever secondary means were employed in producing it, whether thick clammy fogs and vapors, according to some; a sandstorm, or the chamsin, according to others; it was such that it could be almost perceived by the organs of touch, and so protracted as to continue for three days, which the chamsin does [HENGSTENBERG].
