'Confessing' in the Bible

and they were being baptized by him in the Jordan River, as they confessed their sins.

And all the country of Judea and all the people of Jerusalem were continually going out to him; and they were being baptized by him in the Jordan River, as they confessed their sins.

All these died in faith [guided and sustained by it], without receiving the [tangible fulfillment of God’s] promises, only having seen (anticipated) them and having welcomed them from a distance, and having acknowledged that they were strangers and exiles on the earth.

I am writing to you, little children (believers, dear ones), because your sins have been forgiven for His name’s sake [you have been pardoned and released from spiritual debt through His name because you have confessed His name, believing in Him as Savior].
