7.What does the writer of Hebrews exhort us to do, with reference to the five beginning doctrines?

To leave them and go on to perfection, to maturity.

The writer means that we are to leave them and proceed further with our discussion of the Christian salvation. However, in the light of the statements in Chapter Two through Five, it also is true that we should press past them in actual practice and seek to enter the rest of God.
