"The ark of the covenant overlaid round about with gold, wherein was the golden pot that had manna, and Aaron's rod that budded, and the tables of the covenant" Heb 9:2

The contents of the Ark speak of the failure of the Israelites.
Idolatry - the tables of the covenant
Ingratitude - the golden pot that had manna
Insubordination - Aaron's rod that budded
