A personal name appearing in the genealogies of 1 Chronicles 11:42, identifying a man from the tribe of Reuben. The name appears among the list of David's mighty warriors, specifically as the father of one of these elite soldiers. Ancient Greek versions transliterate it as Saiza or Sizai, preserving the consonantal structure while adapting to Greek phonology. Like many biblical personal names occurring only once, the etymology remains uncertain, though it may be related to roots meaning 'look' or 'see.'
