You have called, as in the day of a solemn assembly, my terrors on every side; There was none that escaped or remained in the day of Yahweh's anger: Those that I have dandled and brought up has my enemy consumed.
That is, the enemies were in there cheering and yelling and all as they were destroying it, much as the voices and cheers and all that once went up in the days of their solemn feasts.
