 Other divine groups were composed of deities with interrelated roles , or who together represented a region of the Egyptian mythological cosmos . There were sets of gods for the hours of the day and night and for each <unk> ( province ) of Egypt . Some of these groups contain a specific , symbolically important number of deities . Paired gods can stand for opposite but interrelated concepts that are part of a greater unity . Ra , who is dynamic and light @-@ producing , and Osiris , who is static and <unk> in darkness , merge into a single god each night . Groups of three are linked with plurality in ancient Egyptian thought , and groups of four <unk> <unk> . Rulers in the late New Kingdom promoted a particularly important group of three gods above all others : Amun , Ra , and Ptah . These deities stood for the plurality of all gods , as well as for their own cult centers ( the major cities of Thebes , <unk> , and Memphis ) and for many threefold sets of concepts in Egyptian religious thought . Sometimes Set , the patron god of the <unk> Dynasty kings and the embodiment of disorder within the world , was added to this group , which emphasized a single coherent vision of the pantheon .
