The Bible does not say to partake in confession with a Priest.  It is something that the Roman Catholic Church itself decreed at the Fourth Council of Lateran in 1215.

The Roman Catholic Church’s basis for Priestly forgiveness comes from John 20 verse 23 where Jesus says to his disciples: “If you forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.” However, this should be read in the knowledge that it is through faith in Jesus’ death and resurrection that we receive forgiveness of sins.  Jesus here is asking his disciples to say when sins are forgiven, or otherwise, but it is not they who give or deny the forgiveness, they merely inform.

For the death he died, he died to sin, once for all…

Romans 6 verse 10

Jesus has died for our past sins and our future sins.  He is not repeatedly dying every time we confess.  He sacrificed himself once, to cover all sins.  We do not need to continually confess our sins to receive that forgiveness.  Our salvation is not dependent on our continued repentance.

There is therefore now no condemnation for those who are in Christ Jesus.

Romans 8 verse 1

Once we have committed our lives to Jesus, we do not need to keep confessing our sins to cleanse ourselves, because there is no condemnation for those who are believers.

For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.

John 3 verse 17

Sure, talk to God about your sin in the same way that you would apologise to a friend or family member who you have wronged or gone against their wishes.  But do so in the knowledge that Jesus has already paid the price for that wrong and those who believe in him live under that grace.  And because of that grace, there is no condemnation for those who believe in him.
