Romans 11:33

“O the depth of the riches, both of the wisdom and knowledge of God, etc..] These words are the epilogue, or conclusion of the doctrinal part of this epistle, and relate to what is said throughout the whole of it hitherto; particularly to the doctrines of salvation by Christ, justification by his righteousness, predestination, the calling of the Gentiles, the rejection of the Jews, and their restoration in the latter day; upon the whole of which, the apostle breaks forth into this pathetic exclamation; the design of which is to show, how much of the wisdom and knowledge of God is displayed in these doctrines, and how small a part of it is known by the best of men, and therefore ought not to…”

“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…”

“O the depth ... - This passage should have been translated “O the depth of the riches, and of the wisdom, and of the knowledge of God.” The apostle has three subjects of admiration. Our translation, by the word “both” introduced here, confines it to two. The apostle wishes to express his admiration of the riches and the wisdom, and the knowledge of God. So the Syriac, Arabic, etc. Our translation has followed the Latin Vulgate. The word “depth” is applied in the Scriptures to anything vast and incomprehensible. As the abyss or the ocean is unfathomable, so the word comes to denote what words cannot express, or what we cannot comprehend; Psalms 36:6, “Thy judgments are a great deep;” 1…”

“O the depth of the riches, and wisdom, and knowledge of God - In the ninth chapter, St. Paul had sailed but in a narrow sea: now he is in the ocean. The depth of the riches is described, Rom 11:35; the depth of wisdom, Rom 11:34; the depth of knowledge, in the latter part of this verse. Wisdom directs all things to the best end; knowledge sees that end. How unsearchable are his judgments - With regard to unbelievers. His ways - With regard to believers. His ways are more upon a level; His judgments "a great deep." But even his ways we cannot trace. Romans 11:34”
