We have sinned, and have committed iniquity, and have done wickedly, and have rebelled, even by departing from thy precepts and from thy judgments:
We have sinned, and have committed iniquity - (cf. Nehemiah's confession, Nehemiah 9:1-38).
Sinned ... committed iniquity ... done wickedly ... rebelled - a climax: meaning respectively, erred in ignorance ... sinned by infirmity ... habitually and willfully done wickedness ... as open and obstinate rebels set ourselves against God.
