How to make a selection from tables in Laravel that are not directly related to each other?

Question

Laravel

So. The point is the following.
There are 4 tables
courses, lessons, messages, teachers
They are related as follows:
Lessons with messages are related as one to many (one lesson can have many messages)
Courses with lessons are related as one to many (a course has many lessons)
Teachers are related to Many-to-many courses (teachers can have many courses, and a course can have many teachers)
. there is still a lot of other garbage, I think the description above is enough.
Tell me how I can get all the comments from the lessons of a particular teacher as correctly as possible through Eloquent.
