Number take cover from rebuke (5)
I believe the answer is:
chide
'rebuke' is the definition.
(I know that rebuke can be written as chide)
'number take cover' is the wordplay.
'number' becomes 'C' (C is an example).
'take cover' becomes 'hide' (I've seen this in another clue).
'c'+'hide'='CHIDE'
'from' acts as a link.
(Other definitions for chide that I've seen before include "Tear off strip" , "lecture" , "Reprove" , "Seeing scold" , "Admonish" .)
