How dynamically generate query with diff number of "where"?

How can I dynamically generate query to the db if I don't know how much filter and update - values will be in the $filters and $updates arrays? Template of the query is below:

$model::where($key_1, '=', $filter1)
            ->where($key_2, '=', $filter_2)
            ->where($key_n, '=', $filter_n)
            ->update([$key_1 => $update_1,
              $key_2 => $update_2,
              $key_n => $update_n
            ]);
