No, you don't need it. In fact it should be very fast. The problem is you extract from Member and Insurance. That gives 22000 multiplied by 14000 records, obviously incorrect. You must select only from Member:

SELECT Member.number, Member.LastName, Member.FirstName, Member.etc ;
FROM Member;
WHERE Member.Number NOT IN ( SELECT Insurance.Number FROM Insurance );
INTO SomeTableOrCursor

This should work pretty fast.
