Site home page showing duplicate text

After I altered the Header code in php homepage theme, I encountered duplicate text on my website home page…The current H code is below:

<h2><?php the_title(); ?></h1>
<?php the_content(); ?><h2><?php the_title(); ?></h2>
<?php the_content(); ?>

[Please post code snippets between backticks or use the code button.]

Please, I need to delete one of the duplicate text on my site’s home page..Wordpress 3.2.1.
Website is https://www.theboaconsulting.com

Thank you in advance….
