How to make use of entities on laravel 5

i have this code

use App\Entities\Job;
use App\Entities\Category;
use App\Entities\City;
use App\Entities\JobType;

$viewModel['categories']= Category::all();
$viewModel['cities'] = City::all();
$viewModel['jobTypes'] = JobType::all();

I want to include once "use Entities" and get access to all Entities.
