How do I add this custom HTML above my WordPress </head> tag
<p>I tried inserting this HTML code in my <code>functons.php</code> file in the <code>enqueue scripts</code> following the <a href="https://bibles.org/pages/highlighter" rel="nofollow">directions</a> "To use the Highlighter on your website, add the following line of HTML just before the closing <code>&lt;/head&gt;</code> tag on every page on your website that should have Scripture references found"</p>

<pre><code>&lt;script id="bw-highlighter-config"&gt;
(function(w, d, s, e, id) {
  w._bhparse = w._bhparse || [];
  function l() {
    if (d.getElementById(id)) return;
    var n = d.createElement(s), x = d.getElementsByTagName(s)[0];
    n.id = id; n.async = true; n.src = '//bibles.org/linker/js/client.js';
    x.parentNode.insertBefore(n, x);
  }
  (w.attachEvent) ? w.attachEvent('on' + e, l) : w.addEventListener(e, l, false);
})(window, document, 'script', 'load', 'bw-highlighter-src');
&lt;/script&gt;
</code></pre>

<p>Here is what my enqueue section looks like in <code>functions.php</code> I tried pasting the above HTML right before the ending add_action function, but then I was left with two add_action functions and my site did not load correctly?</p>

<pre><code>/**
 * Enqueue scripts and styles.
 */
function west_scripts() {

        wp_enqueue_style( 'west-style', get_stylesheet_uri() );

        if ( get_theme_mod('body_font_name') !='' ) {
            wp_enqueue_style( 'west-body-fonts', '//fonts.googleapis.com/css?family=' . esc_attr(get_theme_mod('body_font_name')) );
        } else {
            wp_enqueue_style( 'west-body-fonts', '//fonts.googleapis.com/css?family=Roboto:400,400italic,500italic,500');
        }

        if ( get_theme_mod('headings_font_name') !='' ) {
            wp_enqueue_style( 'west-headings-fonts', '//fonts.googleapis.com/css?family=' . esc_attr(get_theme_mod('headings_font_name')) ); 
        } else {
            wp_enqueue_style( 'west-headings-fonts', '//fonts.googleapis.com/css?family=Montserrat:400,700');
        }

        wp_enqueue_style( 'west-fontawesome', get_template_directory_uri() . '/fonts/font-awesome.min.css' );

        wp_enqueue_script( 'west-skip-link-focus-fix', get_template_directory_uri() . '/js/skip-link-focus-fix.js', array(), '20130115', true );

        if ( is_singular() &amp;&amp; comments_open() &amp;&amp; get_option( 'thread_comments' ) ) {
                wp_enqueue_script( 'comment-reply' );
        }

        if ( get_theme_mod('blog_layout') == 'masonry-layout' &amp;&amp; (is_home() || is_archive()) ) {
                wp_enqueue_script( 'west-masonry-init', get_template_directory_uri() . '/js/masonry-init.js', array('jquery-masonry'),'', true );
        }

        wp_enqueue_script( 'west-main', get_template_directory_uri() . '/js/main.js', array('jquery'), '', true );

        wp_enqueue_script( 'west-scripts', get_template_directory_uri() . '/js/scripts.min.js', array('jquery'), '', true );

add_action( 'wp_enqueue_scripts', 'west_scripts' );
