Albert Barnes Commentary Esther 2:19

"And when the virgins were gathered together the second time, then Mordecai was sitting in the king`s gate." — Esther 2:19 (ASV)

When the virgins ... - Rather, “when virgins” and so on. The words begin a new paragraph. There was a second collection of virgins (after that of Esther 2:8), and it was at the time of this second collection that Mordecai had the good fortune to save the king’s life.
