GREEK: καὶ ἐπέταξεν ὁ βασιλεὺς Μαρδοχαίῳ θεραπεύειν ἐν τῇ αὐλῇ, καὶ ἔδωκεν αὐτῷ δόματα περὶ τούτων.
ENGLISH (draft-awaiting-approval): and the king appointed Mordecai to serve at the court, and gave him gifts for this.

PARALLELS:
- [Verbatim] Tosefet le-Esther, בגתן ותרש (Tosefet le-Esther (he.wikisource editorial page: Additions to Esther in Hebrew)) — conduit: medieval retranslation. 'ולמרדכי צוה המלך לעמוד בבית מלכותו ויתן לו מתן רב' directly renders Addition A's appointment to court service and gift, not in MT.
- [Flagged] Yalkut Shimoni on Nach 1053:29 (Yalkut Shimoni on Esther (Remez 1046-1061)) — conduit: lost intermediary. The king removes Bigthan and Teresh and installs Mordecai in their place as court guard — a specific replacement-appointment matching the plus; MT only records that Mordecai's report was written down, not that he was appointed to their post.
- [Flagged] Rashi on Megillah 16b:17:1 (Rashi on Bavli Megillah 9a-17a) — conduit: oral. 'He abandoned Torah and entered office' matches the same specific event -- Mordecai's court appointment -- Addition A reports as the king's reward.
- [Motif] Rashi on Megillah 16b:18:1 (Rashi on Bavli Megillah 9a-17a) — conduit: oral. Mordecai becoming an officer between the two census counts is the same court appointment Addition A reports.
- [Motif] Yalkut Shimoni on Nach 1053:35 (Yalkut Shimoni on Esther (Remez 1046-1061)) — conduit: lost intermediary. 'העביר שני קלסנטרין ומושיב הברברי הזה' states from the enemies' side the same replacement-appointment of Mordecai to the eunuchs' post that the plus describes; not MT material.
