Commanding heights are recognized as positions of power and advantage. They are also closer to the sky on mountains and hills, which are thought to be the home of the gods. Nations chose heights and hilltops as places of worship. Leafy trees are also a favored location because of the shelter and shade they provided in a hot climate, and because they reach all realms of creation—the underworld, the physical world, and the heavens. In the absence of trees, carved poles serve as portable tree shrines honoring the goddess Asherah.
