"On His Blindness"

    
   This poem clearly alludes to a parable that Jesus told about 3 servants and their talents (found in Matthew 25).
   John Milton hints at the story when he states: 

   '...That one talent which is death to hide...'. 
   
  He is alluding to the unfaithful servant who buried the talent in the ground instead of using it to multiply the talent while his master was away. When the master returned, he punished the unfaithful servant and threw him 'outside into the darkness where there was weeping and gnashing of teeth'.
   The poem continues to allude to the parable, and state:

   'Either man's work or his own gifts, who best Bear his mild yoak, they serve him best, his State is Kingly.'

   Meaning that those who serve the master (GOD) best and use what is given to them wisely, will be richly rewarded.
