SUCCINCT SUMMARY
----------------
Rashi frequently makes powerful inferences from the alignment
of ALMOST similar verses. The minor variations between these
almost similar verses suggests nuances and differences.or
even meaning.

EXAMPLE Gn19-02c vs Gn18-04
---------------------------
- Gn18-04 states Abraham offered WASHING and RESTING
- Gn19-02c states Lot offered INNING and WASHING

Rashi noting the reversed order conjectures that
because of the evil hostile nature of Sedom towards
strangers that Lot did not want the guests washing
immediately (Inn 1st, wash 2nd). That way if he got
caught doing hospitality he could say THEY JUST CAME

EXAMPLE Gn19-09b Gn19-11a
-------------------------
Recall that the Sedomites had come as a herd to rape the
Angels. The Sedomites sought to break into the house.

We now read the verses Gn19-06:11 as follows
----------------------------------------------------------------
- Lot left the house to dissuade the Sedomites from rape
- Lot closed the door of the house
- The crowd did not listen---they tried to break in
- The Angels brought Lot into the house
- While bringing Lot in some people entered the ENTRANCE
- But Angels (re)closed the [DOOR]
- Because the angels [HAD ALREADY BLINDED] the Sedomites in
the doors [ENTRANCE]
----------------------------------------------------------------
Rashi makes his inferences based on
- the contrast of DOOR vs ENTRANCE
- use of the past perfect (HAD ALREADY BLINDED

So the picture we get is that after the angels brought Lot into
the house the people tried to break thru and grab the angels...
but the angels blinded them(that is those in the entrance of the
house)...and while they were groping the Angels re-closed the
door. The set of verses shows how evil the Sedomites were and
how brave Lot was in trying to defend his guests.
