Genesis 19:10-11
blindness <05575> [with blindness.]
The word {sanverim,} rendered "blindness," and which occurs only here, and in 2 Ki 6:18, is supposed to denote dazzlings, deceptions, or confusions of sight from excessive light; being derived by Schultens, who is followed by Parkhurst, from the Arabic {sana,} to pour forth, diffuse, and nor, light. Dr. Geddes, to the same purpose, thinks it is compounded of the Arabic {sana,} which signifies a flash, and or, light. The Targums, in both places where it occurs, render it by eruptions, or flashes of light, or as Mercer, in Robertson, explains the Chaldee word, irradiations.
