1. simply add this above your loop

   $args = array(
       'posts_per_page' => 10,
       'category__in' => array( 2, 6 ), //change and add the category ids here
       'orderby' => 'date',
       'order' => 'ASC')
   query_posts($args);

   By popular demand 🙂
   here is another example to doing the same but using tax_query

   $args = array(
       'tax_query' => array(
           array(
               'taxonomy' => 'category',
               'field' => 'slug',
               'terms' => array('category1','category2') ////change and add the category slugs here
           )
       )
       'posts_per_page' => 10,
       'orderby' => 'date',
       'order' => 'ASC')
   query_posts($args);

2. Have a look at the category query parameters here:

3. The easiest way to do this is to have use the category name in the query before the loop starts.

   <?php query_posts($query_string . '&category_name='Your Category, Another Category'); ?>
   
   <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
   

   I haven’t tested it but should work.
