Hebrews 5:11-6:3.
Having just mentioned Jesus being a high priest after the order of Melchizedek, this truth has admittedly taken us out into the deeper currents of our Christian faith. So before moving forward into the depths the Author pauses to shepherd his people. They have grown cold toward hearing these truths revealing a spiritual immaturity. Therefore, the Author calls them to lay aside spiritual immaturity and press on to spiritual maturity.
