33. Oh, the depth, &c.--The apostle now yields himself up to the admiring contemplation of the grandeur of that divine plan which he had sketched out.
      of the riches both of the wisdom and knowledge of God--Many able expositors render this, "of the riches and wisdom and knowledge," &c. [ERASMUS, GROTIUS, BENGEL, MEYER, DE WETTE, THOLUCK, OLSHAUSEN, FRITZSCHE, PHILIPPI, ALFORD, Revised Version]. The words will certainly bear this sense, "the depth of God's riches." But "the riches of God" is a much rarer expression with our apostle than the riches of this or that perfection of God; and the words immediately following limit our attention to the unsearchableness of God's "judgments," which probably means His decrees or plans (Ps 119:75), and of "His ways," or the method by which He carries these into effect. (So LUTHER, CALVIN, BEZA, HODGE, &c.). Besides, all that follows to the end of the chapter seems to show that while the Grace of God to guilty men in ChristJesus is presupposed to be the whole theme of this chapter, that which called forth the special admiration of the apostle, after sketching at some length the divine purposes and methods in the bestowment of this grace, was "the depth of the riches of God's wisdom and knowledge" in these purposes and methods. The "knowledge," then, points probably to the vast sweep of divine comprehension herein displayed; the "wisdom" to that fitness to accomplish the ends intended, which is stamped on all this procedure.
