Answer:
Religious duties quite often are connected with the office of chieftain, who is also priest or seer and rainmaker—all in one. Correspondingly, in nontribal societies, cultic functions belong to the office of the king. In the 3rd dynasty of Uruk, Lugalzaggisi is described as king of the country, priest of the god Anu (the god of the heavens), and prophet of Nisaba (goddess of grasses and writing).
When a division of functions evolved, the intrinsically royal priestly and other cultic functions were transferred to priests, seers, and other servants of the cult; the old concept of the king as priest, however, survived in some fashion for thousands of years. The Egyptian king was the chief priest of the land and the superior of all priests and other cult functionaries. In many images he is portrayed as presiding over the great festivals and bringing offerings to the gods. Later priests carried out their functions as his representative. In Mesopotamia the king was viewed as the cultic mediator between god and man. As head of all of the priests of the country, he had important cultic functions at the New Year’s festival. In critical situations, the king might issue an oracle of blessing; through him the land would be promised salvation, which was often accompanied by the words, “Fear not!” The Persian king performed the sacrifice at the horse offering and was also the “guardian of the fire.” In all questions of religion he was the highest authority; he was also the most cultivated of the magicians. The king in Ugarit (in Canaan) also carried out priestly functions and as prophet was the receiver of revelations. Like other ancient Middle Eastern monarchs, the Hittite king was the chief priest.
The relationship between sacred kingship and priestly cultic functions has extended over widespread geographic areas and historical eras: East Asia, China, Japan, India, Europe (among the Germanic and Scandinavian kings), Africa (in the great empires), and Madagascar. Sometimes the division of functions brought about a transfer of the royal title to those who carried out cultic functions. In Africa from the earliest times there was a type of king who was called lord of the earth; he originally combined political and cultic functions but, with changing times, retained only the cultic ones. The strict separation of the priestly office from that of the king, as in India, where king and priest belong to different castes—Kshatriya and Brahman, respectively—is an unusual exception, however.
The king may be the recipient of a direct revelation of the will of a god. Thus, in Egypt the pharaoh received a divine oracle through dreams in the temple (a practice known as incubation). In Mesopotamia the duty of the king to ascertain the will of the gods was more strongly emphasized; a directive of the gods could result from omens, dreams, or reading the entrails of offerings. All major undertakings of the king were dependent on directives of the god, who was to be consulted in advance. A direct divine revelation to a king is related in the Hebrew Bible in I Kings, chapter 3, which tells of a dream of the 10th-century-BC Israelite Solomon in which he received the promise of the gift of wisdom. Likewise in Genesis, chapter 41, Yahweh, god of the Hebrews, gives the pharaoh a directive in a dream.
