When he opened the supernatural 'box', an unknown power was released.

He put the matchbox in his pocket.

My piggy bank is already full.

The Ark of the Covenant is a sacred box described in the Old Testament.

He put money into the offertory box.

He is a box believer, so he buys a new game as soon as it comes out.

He calls that business a cash cow.

There is not a single letter in my mailbox.

He made a plan to build an ark.

The story of the Ark is shared among many cultures around the world.
