It’s not just Protestants who advocate confessing directly to God.
Those OT passages show that the Jews did it as well.
This, then, is how you should pray: Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven. Give us today our daily bread. And forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from the evil one.'" - Matthew 6:9-13
they had no choice....we do.
