How to create relationship through other model Laravel?

I have some models in my project with differents relations detailed in this picture:

I created some models to represents each tables.

And I would to know if there is a possibility to create relationship that allows to recover all the students of teachers or all the teachers of students.

Example:

class Student extends Model
{
    public function clases(){
        return $this->hasMany(Clase::class, 'student_id');
    }

    /** This function doesn't works, not the great relation */
    public function teachers(){
        return $this->hasManyThrough(Clase::class, Teacher::class, 'student_id', 'teacher_id');
    }
}

I'm using Laravel 5.8

Thank in advance
