Stored Procedure - running a INSERT with dynamic variables

I am trying to run something similar to this within a stored procedure in Oracle.

pWhereClasue2 is generic which I set depending on the table I am working on. The following code runs just if I have the proper defined where clause, but If I try to use this variable, I keep getting errors. I have tried to use ||, single quotes, but nothing has worked. I am not an expert at Stored Procedure. But any help would be appreciated. I am just trying to figure how I can keep this generic and have this code work with pWhereCLAUSE working

INSERT INTO ABC

SELECT * FROM ABCD pWhereCLAUSE to_char(dateOne, 'DD-MON-YYYY') and ROWNUM <= variable1;

commit;
