Also in the great temple in Jerusalem, after the animals' were sacrificed and burned, what happened to the remains (ash, etc.)?
In Bronze age mesopotamia, after the amorites moved in, many sacrifices were buried under structures. For example, after dedication of a temple, an animal sacrifice would be buried in a pit underneath. Relatedly, bodies were buried essentially in the backyards of their family's houses, which led to very few houses being bought or sold.
