Daniel 9:5 - Matthew Poole's English Annotations on the Holy Bible

As if he had said, We are not only sinners, but our sin is wickedness aggravated to the height: thus much the gradation here intimates, by doing wickedly and rebelling. In our confessions of sin to God there must be no mincing nor cloaking of sin, but a full and naked discovery, with selfjudging and self-abhorrence. Note here, all along after, this holy man Daniel puts himself in the number of the greatest sinners: so when we are suppliants and penitents, we must include ourselves in the general petition.
