How to assign multiple unique page ids with the below code –

i have tried 'ID' => array('ID1, ID2, ID3), but not worked.

function publishhome() { 
    $time = current_time('mysql');
    $arg = array(
    'ID' => 16696, //here
    'post_date'     => $time,
    'post_date_gmt' => get_gmt_from_date( $time ),
    'post_status' => 'publish'
);
wp_update_post( $arg );
}
