Host do domu

... Bůh do domu.

A saying something like "In welcoming a guest to your home you also welcome God."
But there's an alternate twist on it I've heard a few times.. "Host do domu..."
I forget the words but there's the same pattern and it means something like "hit him with a stick!"

Anyone know what I'm talking about?

Got any other alternate versions of common sayings?

 

What came first to my mind is this one:

Host a ryba třetí den smrdí.

 

Host do domu, hůl do ruky.

 

The bilbax one is the one I was trying to remember
