The term "bury" usually refers to putting a dead body into a hole or other burial place. The term "burial" is the act of burying something or can be used to describe a place used to bury something.
* In Bible times, dead people were often buried in a cave or similar place. After Jesus died, his body was wrapped in cloths and placed in a stone tomb that was sealed with a large boulder.
* Sometimes the word "hide" can mean "bury" as when Achan hid things in the ground that he had stolen from Jericho. This meant he buried them in the ground.
