The Benediction element of the ceremony is given at the closing of the ceremony, preceding the Announcement as Newlyweds.
It can be an expression of good wishes, a giving of a blessing or some sage advice and words of wisdom.
Scripture, poems and prayers are often used for the benediction.
While reading the benediction it is common for the officiant to hold their arm up as a symbolic gesture of giving a blessing and/or as a gesture of authority.
