There were some books and sections of existing canon that were disputed and turned down for various reasons. The Roman Catholic Church gathered many, not all, of these books together and added them in the mid 16th century and called them the Apocryphal, or "Hidden", books. Most, if not all, of the books in the Apocrypha were written during the intertestamental period between Malachi and the Coming of John the Baptist.

According to the prophet Micah, there was to be a period of Darkness where God will not speak to the prophets. This period was to begin with the Israelites coming back to their land and was to end with the Coming of the Messiah. The Prophet Malachi, the last prophet of the Old Testament, prophesied during the post-exile period. He also prophesied that Elijah was to come before and prepare the way for the Messiah. The time between Malachi and John the Baptist, identified as Elijah by Jesus, was that period of Darkness. For the Apocrypha, proven to have been written during this time, to be divinely inspired, a requirement of canonization,

God had to have spoken to the writers. Therefore, he would've violated his own word, and would've been a liar. Therefore, the apocryphal books cannot be divinely inspired, and, as such, not canon.
