Genesis 19:11  (King James Version)
And they smote the men that were at the door of the house with blindness, both small and great: so that they wearied themselves to find the door.

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.
