'Confessing' in the Bible

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

They were baptized by him in the Jordan, confessing their sins.

All the country of Judea and all those of Jerusalem went out to him. They were baptized by him in the Jordan river, confessing their sins.

Many also of those who had believed came, confessing, and declaring their deeds.
