Poem about child who lived in biblical nation? (7)

I believe the answer is:

edomite

'who lived in biblical nation?' is the definition.
(someone who lived in the ancient kingdom of Edom)

'poem about child' is the wordplay.
'poem' becomes 'ode' (ode is a kind of poem).
'about' says the letters should be written backwards.
'child' becomes 'mite' (I've seen this in other clues).
'ode' written backwards gives 'edo'.
'edo'+'mite'='EDOMITE'

(Another definition for edomite that I've seen is " who lived in old kingdom?".)

I've seen this clue in The Times.
