That doesn't make any sense.  See FGB s.v. "daor", para. 3.
"Hard, severe; costly (in effort, in suffering).  'Ní bheidh
Dia daor orainn', God will not be to hard on us.  'Bhí an
ghaoth daor orainn', we had an unfavourable wind.  'Ba dhaor
an turas orm é', I paid dearly, suffered, for that journey."
