GREEK: Ἔτους δευτέρου βασιλεύοντος Ἀρταξέρξου τοῦ μεγάλου βασιλέως τῇ μιᾷ τοῦ Νεισὰ ἐνύπνιον ἴδεν Μαρδοχαῖος ὁ τοῦ Ἰαείρου τοῦ Σεμεείου τοῦ Κεισαίου ἐκ φυλῆς Βενιαμείν,
ENGLISH (draft-awaiting-approval): In the second year of the reign of Artaxerxes the great king, on the first day of Nisan, Mordecai son of Jair, son of Shimei, son of Kish, of the tribe of Benjamin, saw a dream.

PARALLELS:
- [Flagged] Yalkut Shimoni on Nach 1056:4 (Yalkut Shimoni on Esther (Remez 1046-1061)) — conduit: medieval retranslation. Witness dates Mordecai's dream to 'בשנה השנית למלך אחשורוש' (the second year of Ahasuerus), matching the plus's dating of the dream to Artaxerxes' second year — a detail with no MT basis at all (MT has no dream).
- [Flagged] Esther Rabbah 8:5 (Esther Rabbah) — conduit: medieval retranslation. ER dates Mordecai's dream 'in the second year of King Ahasuerus,' the same regnal-year datum as Addition A's date; MT never narrates this dream at all, so the shared year is a specific non-MT detail (genealogy/tribe is not supplied).
