How can I query a has-many-through relationship in Laravel

What are some ways to query this type of relationship in Laravel

Tables:

• Users
• Roles
• Privileges

Where:

• Each role has a set of privileges
• Each user can belong to many roles
• The User has many privileges through Roles
• Users and Roles are related through an intermediate table. So there is no user_id column on the Roles table

In effect I'm trying to do something like:

User()->Roles()->Privileges()->get() 

but I'm not sure of the laravel way to do this
