Now therefore, our God—the great and mighty and awesome God, keeping covenant and steadfast love—do not treat lightly all the hardship that has come upon us, upon our kings, our officials, our priests, our prophets, our ancestors, and all your people, since the time of the kings of Assyria until today. You have been just in all that has come upon us, for you have dealt faithfully and we have acted wickedly; our kings, our officials, our priests, and our ancestors have not kept your law or heeded the commandments and the warnings that you gave them. (NRSV Nehemiah 9:32-34)
Now therefore, our God, the great, the mighty, and the terrible God, who keepest covenant and mercy, let not all the trouble 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. Howbeit thou art just in all that is brought upon us; for thou hast done right, but we have done wickedly: Neither have our kings, our princes, our priests, nor our fathers, kept thy law, nor hearkened unto thy commandments and thy testimonies, wherewith thou didst testify against them. (KJV Nehemiah 9:32-34)
Ezra confesses that the disloyalty is really all on Israel's side, that God's actually been more merciful and loyal than the people deserved. They only got what was coming to them because of their disobedience, but the great and powerful Oz—sorry, we meant God—didn't forget the covenant.
