In his commentary on the Psalms, Konrad Schaefer shows a “pattern of sevens” that permeates Psalms 96–99. In a section of the Psalter that already demonstrates remarkable structure, these “septets” (a group of seven) add to the unity and message of Book IV in the Psalms.
Let’s hear what Schaefer says about these septets, and then consider the merit of his observations. Why should we care about these groups of seven? (Hint: It may have something to do with the number of perfection).
