'Confessing' in the Bible

Let thine ear now be attentive, and thine eyes open, to hear the prayer of thy servant, which I pray before thee at this time, day and night, for the children of Israel thy servants, confessing the sins of the children of Israel, which we have sinned against thee: both I and my father's house have sinned.

And whilst I was speaking, and praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before Jehovah my God for the holy mountain of my God;

and were baptised by him in the Jordan, confessing their sins.

And there went out to him all the district of Judaea, and all they of Jerusalem, and were baptised by him in the river Jordan, confessing their sins.

And many of those that believed came confessing and declaring their deeds.

By him therefore let us offer the sacrifice of praise continually to God, that is, the fruit of the lips confessing his name.
