Nbu

In Mandaeism, ʿNbu, Nbu, or Enbu is the Mandaic name for the planet Mercury. Nbu is one of the seven planets, who are part of the entourage of Ruha in the World of Darkness. This name was borrowed from the Mesopotamian god called Nabu.
Nbu is associated with learning and scribes, as well as Jesus and Christianity. For example, in Qulasta prayer 210 and Right Ginza 1.4, Nbu is described as "learned and wise". Other names for Nbu include Maqurpiil, Mšiha, and ʿaṭarid. Nbu's name is derived from the Akkadian Nabû.
Buckley suggests a connection between Dinanukht and Nbu. For instance, in the Zrazta ḏ-Hibil Ziwa, Nbu is the Lord of Books, Ink, and Wisdom. Similarly, Dinanukht is called the "ink-book of the gods" in Right Ginza 6.
