How the Bible Self-Testifies to its own Divine Origins
Although there are multiple human authors of Hebrew scripture1 (the Torah+Tanakh, or Old Testament) they are secondary to God. Only humans write, so everything that ever has been written was penned by human authors. This includes all the books of the Bible (Tanakh + New Testament), the Talmud, the Hindu Vedas, the Bhagavad Gita, the Qur’an, and every other purported holy book. According to its own witness, the primary author of biblical Scripture is always God himself. In its multiple genres, all the scriptures of the Tanakh are regarded within itself as divine revelation and recorded as Holy Scripture, the LORD’s words and thoughts.
 …as there must surely also be for the Qur’an.
