Birtum

[3] His sukkal (attendant deity) was the god Eturammi (also spelled Eturame),[4] whose name means "do not slacken.

[7] In a single source the names of the pair are explained as "Lugal-irra and Meslamta-ea of MAR.KI"[8] Wilfred G. Lambert proposed that originally Birtum was worshiped alongside Nungal in a presently unknown city which declined in the third millennium BCE, which lead to transfer of its tutelary deities to Nippur.

[9] A well known example of such a process is the case of Nisaba, whose cult was transferred from Eresh, which disappears from records after the Ur III period, to Nippur.

[10] In a late version of the myth of Anzû, Enlil asks his assistant Nuska to summon Birtum.

[11] While the fragment in which he explains to Birtum why he needs his help is missing, in the subsequent section of the text he congratulates Ninurta (who he addresses as his lord) on behalf of Enlil and urges him to return the Tablet of Destinies after his defeat of Anzû.
