 The decree by Ptolemy V written on the Rosetta Stone appears in three languages.
-==9. Name some of the symbols that appear almost like codes used in Bible prophecies and be able to explain their meanings.== <!--T:16-->
+<noinclude></translate></noinclude>
-==10. Know what a transposition cipher is and how to encode and decode a message using it.== <!--T:17-->
+<noinclude></translate></noinclude>
 A transposition cipher is a method of encryption by which the positions held by units of plain text are shifted according to a regular system to create the cipher text.
-==11. Know what a substitution cipher is and how to encode and decode a message using it.== <!--T:18-->
+<noinclude></translate></noinclude>
 A substitution cipher is a method of encryption by which the units of the plain text are replaced with other symbols which need not be the same as those used in the plain text.
