How did the Hittite-Egyptian treaty describe the roles of the weather god of Hatti and the Egyptian sun god?

In the context of the diplomatic relations between the two powers, the Hittite-Egyptian treaty describes the roles of the weather god of Hatti and the Egyptian sun god as the divine entities that established the relations between their respective lands. Specifically, the treaty states that it was created for the purpose of making eternal the relations that the sun god [of Egypt] and the weather god [of Hatti] had established for the Land of Egypt and the Land of Hatti.1
