The book of Enoch belongs to the so-called Pseudepigrapha books and was apparently written during the first century B.C.--even though some claim that it was written before then.
The Apocrypha are a collection of books, which were written in Greek by various individuals from about 400 to 200 B.C. The Catholic Church considers some of these books as inspired Scripture.
At the Council of Trent (1546 A.D.), the Catholic Church declared that some apocryphal books, together with unwritten Catholic tradition, are of God. It was stated that those who disagreed with this decision were to be considered "anathema."
The Roman Catholic Church (as well as the Greek Orthodox Church) consider the following Apocrypha (which are also referred to as Deuterocanonical books) as inspired:
Tobit or Tobias
Judith
Wisdom of Solomon
Jesus Sirach (Ecclesiasticus)
Baruch (including the letter of Jeremiah, Baruch 6)
The book of Zechariah is an extraordinary inspired book which contains unique insights into the workings and the mind of God.
Zechariah's Hebrew name, "Zekar-yah," means "Yahweh Remembers," or "Yahweh Has Remembered." This name is related to the message of the prophet: God remembers His people and will not forget their work for Him, if they follow Him faithfully.
We mentioned in a prior Update, when discussing the vision of the High Priest Joshua in Zechariah 3:1-10, that Joshua is a type of Jesus Christ. This fact becomes even more obvious in the passage, which describes the coronation of Joshua.
Zechariah 6:9-15 reads:
When we read certain historical books, we may find something like the following narrative, as adopted from sources published on the Internet:
The process of canonization was complex and lengthy. In the first three centuries of the Christian Church, there was no New Testament canon that was universally recognized. Nevertheless, by the 2nd century there was a common collection of letters and gospels that a majority of church leaders considered authoritative. These contained the four gospels and many of the letters of Paul. Justin Martyr, Irenaeus, and Tertullian (all 2nd century), held these to be on par with the Hebrew Scriptures as being divinely inspired. Other books were held in high esteem, but were gradually relegated to the status of New Testament apocrypha.
We explained in an earlier Q&A on Zechariah's vision of the four chariots (in Zechariah 6:1-8), as well as in our free booklet, "Angels, Demons and the Spirit World," that the horses mentioned in this first vision, as well as other visions in the book of Zechariah, describe angels or spirit beings. Angels can appear or manifest themselves in the form and shape of animals, including horses, as well as men. In Zechariah's first vision, which begins in Zechariah 1:8, angels manifest themselves both as men and as horses. Notice the exact wording:
As a first step in answering this question, we need to consider what the New Testament is. Why is there even such a collection of books and letters that report on events from the first century A.D.? Are these merely the random writings of an influential religious movement that have found their way into the literature of the present time?
Or, as the New Testament claims for itself, is this part of the inspired Word of God? Understanding who preserved the New Testament adds even more proof about the unquestionable authority of this part of the Bible that we now possess!
What is the New Testament? Consider the following summary statement given in the “Illustrated Dictionary of the Bible,” Herbert Lockyer, Sr., Editor, 1986:
The famous woman Rahab who helped the spies at the time of Joshua, is clearly identified in the Bible as a harlot or a prostitute. This is the obvious conclusion, when we just accept the relevant Scriptures on their face value.
As it is rightly pointed out in the question, the punishment, as described in the book of Zechariah, deals foremost with the MODERN descendants of the ancient houses of Israel and Judah. It will be inflicted on them just prior to the return of Jesus Christ.
We understand that the modern descendants of the houses of Israel and Judah include the peoples of the USA, Great Britain, Canada, Australia, New Zealand and South Africa, as well as the modern Jews (who live inside and outside the state of Israel). For more information, please read our free booklet, "The Fall and Rise of Britain and America."
As we will see, the entire Word of God that was written down to become a part of what is called the “Bible,” has been preserved through various copies and translations and is available to us, today!
However, the question arises as to which manuscripts should be included and actually constitute the true Scriptures of the Bible. Major religions differ on this most vital consideration. For instance, the Jewish religion uses only those books commonly called the Old Testament, Hebrew Bible or Tanakh. Modern copies are primarily based on the Masoretic Text that dates from between the seventh and tenth centuries AD. None of the New Testament books are accepted as a part of the Hebrew Bible.
