There were no boundaries in the old world.
People do love and treat illegal immigrants with love because they dont kill them.
Illegal immigrants are killing us, they are the ones that dont love.
They are stealing resources, jobs, money, food, and healthcare.
They are breaking and ignoring immigration laws already placed into civil society.
The immigrants the passage is speaking about are nomads that wonder into your land "temporarily" finding refuge for a time, but they will eventually be on their way.
The immigrant of today are not the immigrants of old, they are not complying with the laws and are hiding out.
