Bind variables Where X in (:B)

Question

Hi
Is there a way to use bind variables in a where in clause (not where =)
Here's my query:
select *
from events
where BE_ID in (:BE_IDS)
and BE_TIME between to_date(:StartDate, 'dd/MM/yyyy HH24:MI:SS')
and to_date(:EndDate, 'dd/MM/yyyy HH24:MI:SS')
order by BE_ID, BE_TIME
I can't define BE_IDS as number since it's a collection of numbers (f.e. 1,2,3,4) but when i try to define it as nvarchar I recieve ORA-01722: Invalid number error.
Any ideas?
