Ninlil was a Mesopotamian goddess regarded as the wife of Enlil. She shared many of his functions, especially the responsibility for declaring destinies, and like him was regarded as a senior deity and head of the pantheon. She is also well attested as the mother of his children, such as the underworld god Nergal, the moon god Nanna or the warrior god Ninurta. She was chiefly worshiped in Nippur and nearby Tummal alongside Enlil, and multiple temples and shrines dedicated to her are attested in textual sources from these cities. In the first millennium BCE she was also introduced to Ḫursaĝkalamma near Kish, where she was worshiped alongside the goddess Bizilla, who was likely her sukkal.

Kumarbi, also known as Kumurwe, Kumarwi and Kumarma, was a Hurrian god. He held a senior position in the Hurrian pantheon, and was described as the "father of gods". He was portrayed as an old, deposed king of the gods, though this most likely did not reflect factual loss of the position of the head of the pantheon in Hurrian religion, but only a mythological narrative. It is often assumed that he was an agricultural deity, though this view is not universally accepted and the evidence is limited. He was also associated with prosperity. It was believed that he resided in the underworld.
