Arisai

Arisai was a son of Haman, killed along with his brothers on the day the Jews defended themselves throughout the Persian empire.

Son of Haman, Killed at Susa

Arisai is named in the list of Haman's ten sons slain at Susa. Es 9:9 records: "and Parmashta, and Arisai, and Aridai, and Vaizatha," as the eighth son in the enumeration. The full list in Es 9:7–10 concludes: "the ten sons of Haman the son of Hammedatha, the Jews' enemy, they slew; but on the spoil they didn't lay their hand" (Es 9:10). Arisai's death is part of the events that established the feast of Purim as a memorial to the reversal of Haman's decree against the Jews.
