'Sins' in the Bible

"My God, I am too ashamed and hurt to turn to you, because we're in our iniquities over our heads. Furthermore, my God, our sins have grown as high as the heavens. We have lived in great sin from the days of our ancestors even until today, and because of those iniquities we, our kings, and our priests have been delivered over to foreign kings, for execution, for captivity, for plunder, and for humiliation, as is the case today.

Ezra arose in front of the Temple of God to visit the apartment of Eliashib's son Jehohanan. While there, he neither ate nor drank because he was in mourning over the sins of those who had returned from exile.
