The New John Gill Exposition of the Entire BibleDeuteronomy 28:27
The Lord will smite thee with the botch of Egypt…
some understand of the leprosy, Of that sort of it called
"elephantiasis", frequent among the Egyptians; (See Gill on 13:2).
Thevenot F9 relates, that when the time of the increase of the Nile
expires, the Egyptians are attended with sharp prickings in their skin
like needles. So Vansleb says F11,
``the waters of the Nile cause an itch in the skin, which
troubles such as drink of them when the river increases.
This itch is very small, and appears first about the arms,
next upon the stomach, and spreads all about the body,
which causes a grievous pain; and not only the river water,
but that out of the cisterns drank of, brings it, and it
lasts about six weeks.''
Though some take this botch to be the botch and blain which the
Egyptians were plagued with for refusing to let Israel go, (Exodus 9:9,10) ;
and with the emerods;
or haemorrhoids, the piles, a disease of the
fundament, attended sometimes with ulcers there; see (1 Samuel 5:9) ;
and with the scab and with the itch:
the one moist, the other dry, and
both very distressing:
whereof thou canst not be healed;
by any art of men; which shows these
to be uncommon ones, and from the immediate hand of God.
