ordecai was a Jew of the tribe of Benjamin. He had originally been a citizen of Jerusalem, but was taken into exile by Nebuchadnezzar the Babylonian (Esther 2:6). In this chapter, we find that Mordecai had a couple of great opportunities that came to him; opportunities to be a tremendous influence upon Ahasuerus and thereby upon the whole empire of Ahasuerus. First, he had a beautiful cousin whom he had taken as his own daughter because she was an orphan (Esther 2:7). Secondly, Mordecai was in a place of privilege in the gate of the king (Esther 2:21).
In Esther 1 we read about how Ahasuerus got drunk and banished his own wife. When he sobered up and realized what he had done to Vashti, he became sorry and lonely. He wanted a wife; a new queen. And, in the search that followed, Mordecai's cousin Esther was selected as one among many virgins who would have a chance to win the king's heart. She was suddenly a potential queen.
In several ways, God's sovereignty is wonderfully perceivable in Esther's climb to prominence. Her beauty was no accident. The favor which she obtained in the eyes of Hegai (the "keeper'' of Ahasuerus' women) was certainly not incidental. And, the superlative love which Ahasuerus felt for Esther over all the many other young ladies was not a product of mere chance (Esther 2:17).
