There was a king Duff or Dub in Scotland about a thousand years ago. He got killed -as happened too often back then - and God, in his anger, hid the sun until the body was found and buried ! This was alluded to in the epic play "Macbeth" which condenses 16 years of Macbeth's peaceful and constructive rule, into but a few months of tumult and treacherous murder & plunder !
Duff was the name of a king of Scotland (c.960 a.d.). When he was assassinated (the fate of MANY kings of those days), God showed His hatred of the deed by not allowing the sun to shine until the body was found and buried ! It took 6 months !
