'Confessing' in the Bible

And while 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 they were baptized of him in the river Jordan, confessing their sins.

And there went out unto him all the country of Judaea, and all they of Jerusalem; And they were baptized of him in the river Jordan, confessing their sins.

Many also of them that had believed came, confessing, and declaring their deeds.
