These section is warning for people who check out when a topic of Scripture seems unnecessary or boring. The topic of Jesus as High Priest was started earlier in the chapter. The discussion will go on two more chapters. Some in the congregation were lazy. The danger of not hearing the word and doing something with it is stunted growth. Some Christians are still like spiritual babies because they do not consume the word of God and use it. They are not ready for stronger doctrines because they have not bothered with the easier ones.
