. . .in Codex Vaticanus (B) the prophets come last, and the poetical books come between the main histories and a smaller group of narrative books: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Ruth, 1 - 4 Kingdoms (I Samuel, II Samuel, I Kings, II Kings), 1 Chronicles, 2 Chronicles, 1 Esdras (Ezra), 2 Esdras (Nehemiah), Psalms, Proverbs, Ecclesiastes (Qoheleth), the Song of Songs, Job, the Wisdom of Solomon, Ecclesiasticus (ben Sira), Esther, Judith, Tobit, Hosea, Amos, Micah, Joel, Obadaiah, Jonah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi, Isaiah, Jeremiah, Baruch, Lamentations, the Epistle of Jeremy, Ezekiel, Daniel. . .The Greek-speaking Christian Church took over the Septuagint, which contained other works and in which, moreover, some of the canonical books included additional sections. . .When the patristic writers (early Christian fathers/authorities) try to enumerate the contents of the Old Testament canon their almost unanimous adherence to the total 22 (24), even when they also mention additional books, indicates that the "Palestinian canon" was accepted without question. . .
The OT Apocrypha book titled 2 Esdras / IV Ezra included this pronouncement/directive = "Make public the 24 books you wrote first, and let the worthy and unworthy read them; but keep the 70 that were written last, in order to give them to the wise among your people. For in them is the spring of understanding, the fountain of wisdom, and the river of knowledge." (chapter 14, verses 45-47)
