Staying and turning to receive old Judge then new (10)

'staying and turning' is the definition.
I can't judge whether this defines the answer.

'to receive old judge then new' is the wordplay.
'to receive' means one lot of letters goes inside another.
'old' becomes 'o' (abbreviation).
'judge' becomes 'J' (abbreviation for judge).
'then' becomes 'so' (both can mean 'therefore' or 'in that case').
'new' becomes 'urning' (I can't explain this - if you can you should give a lot more credence to this answer).
'o'+'j'='oj'
'oj' inserted into 'so' is 'sojo'.
'sojo'+'urning'='SOJOURNING'

Can you help me to learn more?
