'Confession' in the Bible

and were baptized by him in the Jordan, making full confession of their sins.

There went out to him people of all classes from Judaea, and the inhabitants of Jerusalem of all ranks, and were baptized by him in the river Jordan, making open confession of their sins.

For with the heart men believe and obtain righteousness, and with the mouth they make confession and obtain salvation.

for it is written, "'As I live,' says the Lord, 'to Me every knee shall bow, and every tongue shall make confession to God.'"
