"... The first (volume of the Studies in the Psalter), the Psalms of the Sons of Korah ... (was) a proposal that the Korah psalms (42-49, 84-85, 87-88) were composed for use at the autumn festival at Dan, and provided a serial psalmody to cover the week's celebrations. ... This is the second volume now, The prayers of David, covering almost all the remaining psalms in Book II, 51-72."--P. 8.
