Another interpretation of "A Psalm of David": This is what the Scripture says (Job 28:13), "Man does not know its value." Rabbi Elazar said: The portions of the Torah were not given in order, for if they had been given in order, anyone who read them would immediately be able to create a world, revive the dead, and perform miracles. Therefore, the order of the Torah was concealed, but it is known to the Holy One, Blessed be He, as it is said (Isaiah 44:7), "And who can proclaim as I do?
Let him declare it and set it forth before Me." Rabbi Jacob bar Acha said: Why is the portion of Absalom juxtaposed with the portion of Gog and Magog? To teach that a wicked son is more difficult for a father than the war of Gog and Magog. Rabbi Joshua ben Levi wanted to sit and arrange this book [of Psalms], but a Heavenly Voice went forth and said to him, "Do not disturb the ancient one."
Rabbi Samuel ben Rabbi Yosi wanted to arrange this book before Rabbi [Judah HaNasi], who said to him (Psalms 111:8), "They are established forever and ever, done in truth and uprightness."
