query twice back

how can i query back twice? i expalin you have a users, posts and favaries tables so i am getting user info from posts table "{{ App\Model\user\user::find($post->poster_id)->name }}" so a user can add posts to his favory list which i am saving with user_id and post_id in favories table then from there using the same algorithm i will get the post info from post_id.

so how to get user info from favories table which will be favory table->post table->user table back forward...
