9 And they said, Stand back. And they said again, This one fellow came in to sojourn, and he will needs be a judge: now will we deal worse with thee, than with them. And they pressed sore upon the man, even Lot, and came near to break the door. 10 But the men put forth their hand, and pulled Lot into the house to them, and shut to the door. 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.
The people of Sodom and Gomorrah took offense that an outsider like Lot would come into their lands and judge them for their behavior. In their wrath they pledged to do even worse to him than they had intended to the visitors that were in his house. The depravity of them in this moment is enormous and mob law reigns supreme.
And there is a notion here that is commonly repeated throughout the scriptures: soothsayers and false prophets will use all manner of clever reasoning to make evil appear palatable, but once evil has the support of the masses, argument and reason can be sidelined. All that matters is that Lot is standing in their way and so any perceived offense is held as justification for whatever hurt they intend on him.
Consider the similarity of this behavior to that in Zechariah 7:11, Acts 7:57, and Acts 19:34. These are three separate accounts of a wicked audience forcing their ears shut so as not to hear the arguments of the righteous, and in one of these cases they even rush to silence God’s messenger with violence.
If one cannot be reasoned with, then how can they be helped? It is understandable why the angels have come to this city to destroy it. Thankfully they were also able to employ some divine intervention to rescue Lot and keep the wicked masses kept at bay.
