Dalphon appears exclusively in the Book of Esther as the second son of Haman listed among those killed by the Jews in Susa. The name is Persian, reflecting the foreign setting of the narrative. Along with his nine brothers, Dalphon was executed and hanged on the day the Jews defended themselves against their enemies—though notably, Esther's decree forbade taking plunder. The ten names in this list have intrigued scholars for their Persian linguistics and the theological significance of their total decimation, ending Haman's line completely.
