Mirmah appears once in 1 Chronicles 8:10, within the genealogical records of the tribe of Benjamin. He is listed as one of the sons of Shaharaim, born in Moab after Shaharaim sent away two wives. These Benjamite genealogies were important for maintaining tribal identity, especially after the exile when establishing legitimate lineage became crucial. The Septuagint renders the name as "Imama" or "Marma/Marmia," showing variant traditions. The name itself possibly derives from a root meaning "deceit," though personal names don't always carry their etymological meaning into usage.
