When it came to the Old Testament, three important facts were considered: 1) The New Testament quotes from or alludes to every Old Testament book but two. 2) Jesus effectively endorsed the Hebrew canon in Matthew 23:35 when He cited one of the first narratives and one of the last in the Scriptures of His day. 3) The Jews were meticulous in preserving the Old Testament Scriptures, and they had few controversies over what parts belong or do not belong.
Pagdating sa Lumang Tipan, tatlong mahalagang katotohanan ang isinasa alang-alang: 1) Ang Bagong Tipan ay mga sipi mula sa Lumang Tipan o tumutukoy sa bawat Aklat ng Lumang Tipan. 2) Inendorso ni Hesus ang Canon ng Lumang Tipan sa Mateo 23:35 ng Kanyang banggitin ang isa sa mga unang salaysay at ang isa sa mga Aklat ng Kasulatan ng Kanyang panahon.
