The book of Hebrews explained to Jews the details of the transition from the Old Covenant to the spiritual reality of the New Covenant. Hebrews is the best book of the bible for explaining the connection of the physical forerunners we read about in the Old Testament to the spiritual realities we read about in the New Testament.
To properly understand a book of the bible, a bird's eye view can be very helpful and this summary by Phil Roberts is a clear, concise and to the point explanation.
