Commentary for Esther 2:21

בַּיָּמִ֣ים הָהֵ֔ם וּמָרְדֳּכַ֖י יֹשֵׁ֣ב בְּשַֽׁעַר־הַמֶּ֑לֶךְ קָצַף֩ בִּגְתָ֨ן וָתֶ֜רֶשׁ שְׁנֵֽי־סָרִיסֵ֤י הַמֶּ֙לֶךְ֙ מִשֹּׁמְרֵ֣י הַסַּ֔ף וַיְבַקְשׁוּ֙ לִשְׁלֹ֣חַ יָ֔ד בַּמֶּ֖לֶךְ אֲחַשְׁוֵֽרֹשׁ׃

in those days, while Mordecai sat in the king’s gate, two of the king’s chamberlains, Bigthan and Teresh, of those that kept the door, were wroth, and sought to lay hands on the king Ahasuerus.
