Again, as we review the history of the Psalter, we are impressed with the many sides of Israel's life and human experience that it represents. Not one, but perhaps fifty or a hundred, inspired souls, laymen, prophets, priests, sages, kings, and warriors, have each clothed the divine truth that came to them or to their generation in exquisite language and imagery, and given it thus to their race and humanity. Successive editors have collected and combined the noblest of these psalms, and the Psalter is the result. The exact date of each psalmist and editor is comparatively unimportant, for though differing widely in origin and theme, they are all bound together by a common purpose and a common belief in the reality and the immediate presence of God. All nature and history and life are to them but the manifestation of his justice and mercy and love. In direct communion with the God whom they personally knew, they found the consolation and peace and joy that passeth all understanding, even though the heathen raged and their foes plundered and taunted them. To that same haven of rest they still pilot the world's storm-tossed mariners. XIII THE FORMATION OF THE OLD TESTAMENT CANON [Sidenote: _Israel's literature at the beginning of the fourth century before Christ_] Could we have studied the scriptures of the Israelitish race about 400 B.C., we should have classified them under four great divisions: (1) The prophetic writings, represented by the combined early Judean, Ephraimite, and late prophetic or Deuteronomic narratives, and their continuation in Samuel and Kings, together with the earlier and exilic prophecies; (2) the legal, represented by the majority of the Old Testament laws, combined with the late priestly history; (3) the wisdom, represented by the older small collections of proverbs; (4) the devotional or liturgical, represented by Lamentations and the earlier collections of psalms. [Sidenote: _The combining of the prophetic and priestly histories_] Even before all the Old Testament books were written, the work of canonization began; before the first large canon was adopted, the prophetic and priestly narratives, and with them the earlier and later laws, were combined. This amalgamation was the work of a late priestly editor. The Pentateuch and its immediate sequel, Joshua, is the result. [Sidenote: _The method of combining_]
