Nehemiah 4:5
And cover not their iniquity, and let not their sin be blotted out from before thee: for they have provoked thee to anger before the builders.
And cover not their iniquity, and let not their sin be blotted out from before thee,.... Let it not go unpunished, and even let it not be pardoned; which is spoken, not from a private spirit of revenge, but from a public spirit for the glory of God, and his justice; and not as a mere imprecation, but as a prophecy of what would be the case, in like manner as many of David's petitions in the Psalms; and for this there was a good foundation, since God had threatened the Moabites and Ammonites with utter destruction:
for they have provoked thee to anger before the builders; by despising his people, and mocking at the work the Lord had called them to; and this they did publicly, and on purpose to discourage the workmen.
