What does Scripture say about confession to a Priest?

Classically, we use the following two verses to support the Doctrine of Priestly confession:

James 5:  The Prayer of Faith

13 Are any among you suffering? They should pray. Are any cheerful? They should sing songs of praise. 14 Are any among you sick? They should call for the elders of the church and have them pray over them, anointing them with oil in the name of the Lord. 15 The prayer of faith will save the sick, and the Lord will raise them up; and anyone who has committed sins will be forgiven. 16 Therefore confess your sins to one another, and pray for one another, so that you may be healed. The prayer of the righteous is powerful and effective.

John 20:  Receive the Holy Spirit

22 When he had said this, he breathed on them and said to them, “Receive the Holy Spirit.  23 If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.”

However, I see the Sacrament of Confession (i.e. Reconciliation) explicitly described here:

Hebrews 13:17Obey your leaders

17 Obey your leaders and submit to them, for they are keeping watch over your souls and will give an account. Let them do this with joy and not with sighing—for that would be harmful to you.

And, explicitly mentioned, here:

2 Corinthians 5 The Ministry of Reconciliation

18 All this is from God, who reconciled us to himself through Christ, and has given us the ministry of reconciliation; 19 that is, in Christ God was reconciling the world to himself,[d] not counting their trespasses against them, and entrusting the message of reconciliation to us. 20 So we are ambassadors for Christ, since God is making his appeal through us; we entreat you on behalf of Christ, be reconciled to God.
