Adam Clarke on Nehemiah 9:3

One fourth part of the day - As they did no manner of work on this day of fasting and humiliation, so they spent the whole of it in religious duties. They began, says Calmet, on the first hour, and continued these exercises to the third hour; from the third they recommenced, and continued till the sixth hour; from the sixth to the ninth; and from the ninth, to the twelfth or last hour.

1. They heard the law read, standing;

2. They prostrated themselves, and confessed their sins;

3. They arose to praise God for having spared and dealt thus mercifully with them.
