He constructed temple for spouse (8)
I believe the answer is:
helpmeet
'for spouse' is the definition.
(helpmeet is a kind of spouse)
'he constructed temple' is the wordplay.
'constructed' indicates an anagram.
'temple' is an anagram of 'lpmeet'.
'he'+'lpmeet'='HELPMEET'
(Other definitions for helpmeet that I've seen before include "Specifically a wife" , "assistant" , "Biblical wife" , "Partner" , "old wife?" .)
