Deuterocanonical

The collection of OT scriptures (i.e. the canon) is repeatedly called the 'law and the prophets': Matthew 11:13, Lk.16:16, Luke 24:27, 44-5, John 5:39. 46, Matt.22:40, Matt.7:12, Matt.5:17, Rom.16:26, Acts 13:15, Acts 24:14, Acts 28:23. The Old Testament canon ends with the law of Moses and the prophet Elijah, (Mal.4:4-6) in other words the witness of the law and the prophets. (Rom.3:21) The next voice we hear is one crying in the wilderness (Mt.3:3, Mk.1:3, Lk.3:4, Jn.1:23, Isa.40:3) heralding the Messiah.

The canon (law & prophets) was already closed and there were no more prophets during the Deuterocanonical writings. (2 Maccabees 15:9, 2:13, Ecclesiasticus 1:1, 1 Macc 4:46, 14:41, 9:27) The question of the canon is a question regarding the providence of God not one that can be answered with history.
Apostles doctrine was at the foundation of the church for the perfecting of the church thus again there would be a finality to this process in their days. (Act.2:42, 1 Cor.12:28, Eph.2:20, 4:11-14, 2 Tim.3:16-7) Inscripturation was in real time (Ac.2:42, 1 Cor.14:37, 2 Pet.3:16, 1 Tim.5:18 w/ Lk.10:7, Ac.13:25, Mt.21:26, w/Jn.1:27, Lk.3:16, 2 Thess.3:14, Rev.1:1-4,11, similarly as with the law and the prophets- Deut. 31:24-26; I Sam. 3:19-21,10:25, 1Kin.4:29-30, Dan. 9:2, Isa.8:20, Mal.2:7 w/ Jer.33:20-1 & 2 Ki.22:8) as the gospel was already delivered by Christ and the apostles (Mt.10:40, Lk.10:16, Jn.13:20) and already being defended. (Lk.1:1-4, Heb.1:1-2, 2:3-4, Gal.1:8-12, Jd.3, Rev.1:11,22:13, Heb.12:2)

The Jews had the oracles of God, the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises. (Rom.3:2, 9:4, Isa.59:21,Mal.2:7 w/ Jer.33:20-1 & 2 Ki.22:8) Even the enemies of Christ in the Jewish leadership “sit in Moses' seat” thus Jesus instructed “All therefore whatsoever they bid you observe, that observe and do”. (Mt.23:2-3, Mal.2:7, Hag.2:11, Jn.11:49-51) The Apocryphal books show up in the intertestamental period after the law & the prophets are recognized as authoritative. This time frame is supported by the fulfillment of Daniels prophecy (Dan.9:24-6) tying the decree of Cyrus according to Isaiah’s prophecy (Isa.44:26-8, 45:1) and the fulfilling thereof in Ezra and Nehemiah’s day under the ministry of Zechariah and Haggai the prophets (Ezra 5:1, 6:14) The next event being the coming of the Messiah. The Old Testament canon was closed until that Prophet should appear. The New Testament never references the apocryphal books directly except the intertestimental book of 2 Maccabees ch.7 which is referenced in Heb.11:35. But this does not indicate canonicity since the Old Testament canon (law & the prophets) was closed as indicated in 2 Macc. 15:9, 2:13. "A few chapters later it endorses the practice of praying for the dead so that they may be freed from the consequences of their sins (2 Macc. 12:41-45)"; obviously heretical. Also relevant is Ecclesiasticus 1:1, 1 Macc 4:46, 14:41, 9:27. Paul quoted from a pagan poet in Ac.17:28 and a Cretian prophet in Tit.1:12, but that doesn't prove them is canon material.
The final 70 weeks place Israel under God's judgment for their sin til the time of the end. Part of God's wrath is his withdrawal of his prophets and revelation. (1 Sam.28:6, Isa.59:1-2, 57:17, 64:7, Deut.32:20, 31:18, Job 13:23-4) Since the beginning of the countdown to the Messiah started with the rebuilding of Jerusalem and the temple, we see the final prophets of the Old Testament directing this rebuilding. (Hag.1:1. Zech.1:1,12, Ezra 5:1, 6:14) And the people still not walking with their God with the whole heart. (Ezra 10:10-44, Neh.13)
“Finally, the books of the Apocrypha abound in doctrinal, ethical, and historical errors. For instance, Tobit claims to have been alive when Jeroboam revolted (931 B.C.) and when Assyria conquered Israel (722 B.C.), despite the fact that his lifespan was only a total of 158 years (Tobit 1:3-5; 14:11)! Judith mistakenly identifies Nebuchadnezzar as king of the Assyrians (1:1, 7). Tobit endorses the superstitious use of fish liver to ward off demons (6: 6,7)!
Wisdom of Solomon teaches the creation of the world from pre-existent matter (7:17). II Maccabees teaches prayers for the dead (12:45-46), and Tobit teaches salvation by the good work of almsgiving (12:9) -quite contrary to inspired Scripture (such as John 1:3; II Samuel 12:19; Hebrews 9:27; Romans 4:5; Galatians 3:11).”(Bahnsen https://reformed.org/bible/the-concep...)
