Matthew Poole and continuators on Genesis 19:11

11 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.

Heb. With blindness, i. e. with a blindness both of Body and mind. It was not a total blindness, as if they quite lost the use of their Eyes, for they saw the house though not the door, but it was a great dimness and confusion of their sight, and a disturbance in their common sense, by which they were made unable to distinguish between differing persons or places; as it was also with the Syrians, 2 King. 6. 18. and as it is in some measure with some drunkards, who, though their eyes be open, cannot distinguish between things that differ. And this was very easie for Angels to do by a small alteration either in their sight or in the Air, whereby either the door might appear to them like the solid wall, or the several parts of the wall like so many doors.
