Ezra 9:4

There were assembled unto me everyone that trembled at the
words of the God of Israel
That had a reverence for the word of God, and the things contained in it; feared to break the laws of God, and trembled at his judgments, which they might apprehend would come upon transgressors, see ( Isaiah 46:2 ) ,

because of the transgression of those that had been carried away;
into Babylon, and were now returned, and which was an aggravation of their transgression:

and I sat astonished until the evening sacrifice:
or until the ninth hour, as the Syriac version, which was about our three o'clock in the afternoon, at which time the evening sacrifice was offered; perhaps it was in the morning when Ezra first received his information from the princes.
