Ḫalki was associated with other grain deities, namely Mesopotamian Nisaba and Hattian Kait, with the latter presumed to be functionally identical.
[7] Nisaba was a Mesopotamian goddess similarly associated with grain,[3] and she is first attested in Anatolia in the Old Assyrian texts from Kanesh as one of the deities of the foreign traders, though there is no indication that she continued to be worshiped there after they abandoned the site.
[10] Taracha notes this is one of the two examples where a Hittite deity was associated in that capacity with a foreign one of a different gender, the other being the case of Lelwani and Allatum.
[2] The male version of Ḫalki, known from the text KBo 52.20 + E 780, apparently was regarded as the husband of Ḫatepinu (otherwise attested as the wife of Telipinu) and of a goddess from Ḫarpiša designated by the Sumerogram dNIN.É.GAL, the brother of tutelary god of Zitḫara (Zitḫariya [de]), and possibly as the father of the weather god of Nerik (presumably a local tradition, compared in scholarship to references to Šulinkatte and the sun goddess of the Earth being his parents).
[17] In contrast with major deities from the local pantheon such as Anna and Nipas, she is chiefly attested in theophoric names, one example being Ḫalkiaššu, an official at the time of king Waršama.
[22] It is presumed the male version of this deity was venerated in the north, but ultimately in most cases it is not possible to distinguish whether it can be assumed that a local hypostasis of Ḫalki was not female.
[26] Textual sources indicate it was located near the "gate of the (water) drawing", presumed to be an entrance to the citadel identified during excavations.
[28] In the same city Ḫalki was also worshiped in the so-called "Great Temple" constructed during the reign of Tudḫaliya IV, which was dedicated to various deities belonging to the state pantheon.
[30] One of the ceremonies held during it involved governors of individual cities of the Hittite Empire presenting grain-based offerings provided by their domains to the king in front of Ḫalki's temple.
