Blains. Exodus 9:9. Pustules rising in the skin. There was first an ulcer and boil inflamed; then the pustules, or blains, broke out on it. This was one of the most fearful of the ten plagues inflicted upon the Egyptians.

It has been thought to be the black leprosy, a virulent kind of elephantiasis, "the botch of Egypt," "a sore botch that cannot be healed," Deuteronomy 28:27; Deuteronomy 28:35; that same disease which afflicted Job. Job 2:7.
