The message is, wake up from your slumber! Anything can happen anywhere. Don’t build your dwellings as if they are permanent,
only temporary.
Do we really want out of this Galus? or are we extremely comfortable living in B.P. F.B. Lakewood, SI, Monsey, Monroe, etc..
Are we really waiting to pack up and go to yerushalayim
on a moments notice?
If you put your trust in society, bank account, so called civility
of your country, community, alarm systems, gated secure mansion,
instead of in HB”H you are not really safe.
This is my interpretation.
