Now in the twenty fourth day of this month , etc.] The seventh month, the month Tisri or September, two days after the feast of tabernacles was ended: the children of Israel were assembled with fasting, and with sackclothes, and earth upon them ; which were all outward tokens of mourning and humiliation, (see Joel 1:8,14 1 Samuel 4:12) which they could not show during the festival; but that being over, they return to it, (see Nehemiah 8:9).
