Our doors are always open

I extracted the text:

Portentum plagens tua si caret asse commena
Pergerian numinis resonat celer intus amice
Si tamen esurit luges maxilla calabit
Ostia nam miseris fraler sunt semper aperta

Which google translates as:

If your plagiarism is lacking, please pay attention to it
The pergerian of the god echoes quickly within the friend
But if he is hungry, his jaws will warm
For the doors are always open to the poor brothers

This is what I think it means:

If you are sick please tend it yourself
As the will of god spreads quickly to your friends
But if you are hungry, you will be fed
For our doors are always open to the poor
