In Mandaeism, Etiná¹£ib Ziwa or êtiná¹£ib Ziwa () is an uthra (angel or divine being) who starts a battle against Nbaá¹Â. Etiná¹£ib Ziwa only appears in a few chapters of the Mandaean Book of John.
In Chapter 3 of the Mandaean Book of John, when Etiná¹£ib Ziwa starts a battle against Nbaá¹Â, he unsuccessfully attempted to strike Nbaá¹ with a sword three times. Nbaá¹ then calls the 21 sons of Yushamin, led by Gubran, to fight against Etiná¹£ib Ziwa. Etiná¹£ib Ziwa proceeds to shoot arrows at Gubran. On the first three attempts, Gubran was able to catch the arrows with his right hand, but on the fourth shot, an arrow struck the forelimb of Paraheil, Gubran's vehicle who is a heavenly steed or warhorse. This provokes an all-out war in which Yawar, Bihram, and Yukabar slaughter all the sons of Yushamin.
According to Chapter 3 of the Mandaean Book of John, Bihrath-Anana is the mother of Etiná¹£ib Ziwa.
