For certainly enough time has elapsed so that [by now] you ought to be teachers, [but instead] you are in need of having someone teach you again the basic principles of God's message. You have become people who need "milk" and not "solid food." [Note: The fundamental truths of Christianity are here figuratively spoken of as "milk," while the more advanced teaching, such as Christ's priesthood being like Melchizedek's, is called "solid food"].

But "solid food" is for mature people, who because of using their [spiritual] senses, have become able to distinguish good from evil.

and that no one becomes immoral or ungodly, like Esau, who sold his right to the firstborn son's inheritance for a single meal.
