Q:

Word order of "Blessed are the meek"

I am wondering why the word order is inverted in these sentences:

Blessed are the meek. 
Blessed are the poor. 

It seems to me that the inversion is relevant to the adjective blessed.  Can someone shed some light on it?  Thanks! 

A:

You can reverse the order of any sentence like this and have it remain grammatical.  Long is the day.  Rumbling is my stomach.  It's not common to do so, but it's acceptable.  This is a particular phrase that, for some reason (probably because of repetition from religious texts), ended up being more common than its reverse.  The meek are blessed is also grammatical, just less common.
