Is it possible for Mathematica to compare a number of lists of different sizes, and delete duplicates in a hierarchical manner?

For example, given the following lists:

list 1list1 = {2, 5, 10, 11, 12, 17, 18};
list 2list2 = {5, 8, 11, 16, 19, 21};
list 3list3 = {5, 8, 9, 11, 16, 19, 21, 23};

I would like to output:

list 1list1 = {2, 5, 10, 11, 12, 17, 18}
list 2list2 = {8, 16, 19, 21}
list 3list3 = {9, 23}

where list 1list1 keeps all its original elements, list 2list2 keeps only elements belonging to list 2list2 and not list 1list1, and list 3list3 keeps only those elements not contained in lists 1 & 2.

If this will take an inordinately long time, I am happy with just comparing the list with the previous list and deleting the duplicates from the second list.

Delete duplicates from hierarchy of lists
