Jehovah (although hidden and not mentioned) providentially cares for His indifferent dispersed earthly people, who are “Lo Ammi.” The Gentile queen (a type of the church) fails to show her beauty (see Ezek. 16:14); the Jewish bride supersedes her. The Gentile opposer of the Jews is judged, and Mordecai is exalted as head. Peace and prosperity flow with rejoicing. It typifies preservation through Gentile supremacy and judgment of their enemies, to deliver them for glory in the Kingdom.
Vashti is set aside for Esther. Haman is set aside for Mordecai. Enemies are set aside for the Jews. Esther was a Benjamite orphan.
The author may have been Mordecai.
B.C. 485-473, 12 years between Ezra 6 and 7.
