I am want to re-ride core function wp_update_user()

In this function there is text This notice confirms that your password was changed on ###SITENAME###. that i want replace with some other word.

I have tried to re-ride as

function wp_update_user($userdata) {
    if ( $userdata instanceof stdClass ) {
        $userdata = get_object_vars( $userdata );
    } elseif ( $userdata instanceof WP_User ) {

    }

    // First, get all of the original fields
    $user_obj = get_userdata( $ID );
    if ( ! $user_obj ) {
        return new WP_Error( 'invalid_user_id', __( 'Invalid user ID.' ) );
    }

    $user = $user_obj->to_array();

    // Add additional custom fields
    foreach ( _get_additional_user_keys( $user_obj ) as $key ) {
        $user[ $key ] = get_user_meta( $ID, $key, true );
    }

    // Escape data pulled from DB.
    $user = add_magic_quotes( $user );

    if ( ! empty($userdata['user_pass']) ) {
        // If password is changing, hash it now
        $plaintext_pass = $userdata['user_pass'];
        $userdata['user_pass'] = wp_hash_password( $userdata['user_pass'] );

}

and add_filter('wp_update_user', 'wp_update_user', 1, 2);

But show error like that you can not re-declare that function again.

So please help me

If I understand you correctly, then you only want to change the text of the mail. This you can do via the filter hook password_change_email. No need to redeclare the function, which you actually can't do. Below you find an example on how to use the password_change_email filter to change your message text.

add_filter( 
  'password_change_email', 
  'wpse207879_change_password_mail_message', 
  10, 
  3 
);
function wpse207879_change_password_mail_message( 
  $pass_change_mail, 
  $user, 
  $userdata 
) {
  $new_message_txt = __( 'Some text ###USERNAME### more text
    even more text ###EMAIL### more text after more text
    last bit of text ###SITENAME###' );
  $pass_change_mail[ 'message' ] = $new_message_txt;
  return $pass_change_mail;
}

I've tested this and it works. Just to clarify, this applies to the use case, in which one changes and updates the password via the backend user management.
