Temporarily in favour of the gift (3,3,7)
I believe the answer is:
for the present
'temporarily' is the definition.
(I've seen this before)
'in favour of the gift' is the wordplay.
'in favour of' becomes 'for' (being for a particular cause).
'gift' becomes 'present' (synonyms).
'for'+'the'+'present'='FOR THE PRESENT'
(Other definitions for for the present that I've seen before include "Extract from thank you letter" , "Temporarily" .)
