'Confessing' in the Bible

may your ear be attentive and your eyes be open to hear the prayer of your servant that I am praying to you today throughout both day and night on behalf of your servants the Israelites. I am confessing the sins of the Israelites that we have committed against you -- both I myself and my family have sinned.

Those truly of Israelite descent separated from all the foreigners, standing and confessing their sins and the iniquities of their ancestors.

For one-fourth of the day they stood in their place and read from the book of the law of the LORD their God, and for another fourth they were confessing their sins and worshiping the LORD their God.
