Clue: In valley, Ezekiel and others pray, continue (2,4)
Answer: DO TELL
Explanation: Definition: pray, continue
An envelope ('in') of OT (Old Testament, 'Ezekiel and others', to identify one book) in dell ('VALLEY'). The definition nicely echoes the antique flavour of the answer as well as adding to the misleading surface reference to the dry bones.
