'Confession' in the Bible

So Joshua said to Achan, “My son, give glory to the Lord, the God of Israel, and make a confession to Him. I urge you, tell me what you have done. Don’t hide anything from me.”

Therefore, make a confession to Yahweh the God of your fathers and do His will. Separate yourselves from the surrounding peoples and your foreign wives.”

While they stood in their places, they read from the book of the law of the Lord their God for a fourth of the day and spent another fourth of the day in confession and worship of the Lord their God.
