From the early Church Fathers to now.
“And Athach going out went to Mardochai, who was standing in the street of the city, before the palace gate:”
“So Hatach went forth to Mordecai, unto the street of the city,.... Where he was, in a public manner, expressing his grief and sorrow: which was before the king's gate: that led to the royal palace.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
