Display Json data in laravel view with Joins

I'm trying to retrieve json data from database to laravel blade view with join associate table.

in my case I have two tables called interesting courses and courses. here some student can have many interesting courses. Courses id stored as json array in database as follows.

["1","11","15","16"] 

but I need to join the courses table to get the associate course name as follows.

["Hospitality","Business Management","Auto Mobile","Health Care"]

How can I do it.
