This proper masculine name belongs to Jesse's fifth son, according to 1 Chronicles 2:14. This makes Raddai one of David's older brothers, though he's never mentioned in the Samuel narratives about David's anointing or life. The absence is striking—1 Samuel 16 mentions David as the youngest of eight sons, but doesn't name all of them. Chronicles preserves the full list, including Raddai, ensuring that even those who played no role in the larger narrative are remembered. The name's etymology is uncertain, and nothing is known about Raddai's life or descendants.
