George Leo Haydock, on Esth 2:21

“At that time, therefore, when Mardochai abode at the king’s gate, Bagathan and Thares, two of the king’s eunuchs, who were porters, and presided in the first entry of the palace, were angry: and they designed to rise up against the king, and to kill him.”

“Bagathan, or Bagatha and Thara, chap. xii. 1. One of the chief counsellors was called Bagatha. (Haydock) — But these two were porters, (Calmet) or guards, of the king, (Septuagint; Grotius) or of the treasury. (Vatable) — Some Greek copies and the Chaldean insinuate that they were displeased at the advancement of Mardochai. The latter supposes that they meant also to poison Esther. (Calmet) — It appears that they wished to make Aman king, (Menochius) and the detection was always resented by him, chap. xii. 6. (Calmet)”
