Vampires of the 14th Psalm

Where did the righteous go?
The generosity  
The body's life blood flow  
Was a delicacy
 
Fully consumed by them
And yet still untasted  
Totally still unseen  
All the good love wasted  
 
For the want of a meme
And so darkness rises  
Beckoning the theme  
Of salvation's prizes
 
And Jacob's own Seed
The Psalmist can't see one  
Not even one of them
Hidden blooms among the weeds
