Based on your inputs your code will be like as mentioned below..

SQL

BEGIN
   // Add appropriate WHERE Condition
   SELECT MAX(id) INTO maxId FROM table2;

   // Add appropriate WHERE Condition in SELECT statement mentioned below
   FOR i IN (SELECT col1,col2 FROM table1)
   LOOP
        INSERT INTO table3 VALUES (maxId, i.col1, i.col2);
   END LOOP;
END;

Please note , You need to do exception handling separately.
