Ezra 11:6

let now thine ear be attentive, and thine eyes open, that thou mayest hear the prayer of thy servant, which I pray before thee at this time, this day [both] day and night, for the children of Israel thy servants, and make confession for the sins of the children of Israel, which we have sinned against thee: both I and the house of my father have sinned.
