Rename pagination

Hi!
How to rename pagination?

https://ibb.co/R7400KR

I use in archive.php and category.php:

<?php twentytwelve_content_nav( 'nav-below' ); ?>

functions.php:

if ( ! function_exists( 'twentytwelve_content_nav' ) ) :
 function twentytwelve_content_nav() {
 global $wp_query;

 $big = 999999999; // need an unlikely integer

 echo paginate_links( array(
 'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
 'format' => '?paged=%#%',
 'current' => max( 1, get_query_var('paged') ),
 'total' => $wp_query->max_num_pages
 ) );
 }
endif;
