The Hebrew in Psalm 2:9 that is translated as “iron rod” or similar in English is translated in the Contemporary Chichewa translation (2002/2016) as ndodo yaufumu or “yokes.” In Chewa culture, this is a rod that is carried by a chief or king. It is a symbol of power and authority. It can either be wooden or metal. Sometimes it is decorated with some ornaments. (Source: Mawu a Mulungu mu Chichewa Chalero Back Translation)
