John Gill Commentary Nehemiah 9:32

"Now therefore, our God, the great, the mighty, and the terrible God, who keepest covenant and lovingkindness, let not all the travail seem little before thee, that hath come upon us, on our kings, on our princes, and on our priests, and on our prophets, and on our fathers, and on all thy people, since the time of the kings of Assyria unto this day." — Nehemiah 9:32 (ASV)

Now therefore, our God, the great, the mighty, and the
terrible God, who keep covenant and mercy
The same titles Nehemiah gives to the Lord, (Nehemiah 1:5) and it may reasonably be thought the whole prayer is his composure, which was delivered by him to the Levites.

let not all the trouble seem little before you;
as if it was not enough; let it be judged sufficient, and no more be added, but mercy shown. Aben Ezra thinks the word "little" is not to be connected with "trouble", but with the nearest antecedent "mercy", and so Gussetius {z}. As if the sense was, let not your mercy be small with you, but let it be largely extended along with all the trouble, or at the time when trouble of every kind

comes upon us, on our kings, on our princes, and on our priests, and on
our prophets, and on our fathers, and on all your people, since the
times of the kings of Assyria unto this day;
but this sense is not clear, and makes it refer to times to come; whereas it relates to past time, and to all the trouble and affliction they had met from the Assyrian kings, from the time they invaded their land, and carried them captive, until this day.
