Show in view only object with specified id

i am woking on a project about a restaurant and i need to show on my staff view only the Chef and Su-Chef which has id (Chef-2, Su-Chef 4). I need to show on my view all the Chefs and all the Su-Chefs. The view is organised at the form that is the number is odd (i have the image on left and text on right), if the number is even i have (i have the image on right and text on left) Here is my Controller

public function index()
{
    $staff = Staff::where('visible','yes')->where('delete','no')->orderBy('name','DESC')->get();
    return view('staff.staff', ['staff' => $staff]);
}

And this is my View
