Charles Ellicott Commentary Romans 11:33

"O the depth of the riches both of the wisdom and the knowledge of God! how unsearchable are his judgments, and his ways past tracing out!" — Romans 11:33 (ASV)

Riches.—The two substantives which follow may be taken as dependent upon “riches.” This is the construction adopted in the Authorised Version, and is expressed by the use of the word “both.” Or all three substantives may be independent, O the depth of the riches, and of the wisdom and knowledge of God! In either case, “riches” means “inexhaustible resources,” implying either that the wisdom and knowledge of God are inexhaustible, or that the materials at their command are inexhaustible. By means of these infinite resources God is able to bring good even out of evil.

Judgments.—Decisions, such as that by which Israel was excluded and the Gentiles admitted.

This grand and comprehensive view of the divine purposes makes so deep an impression upon the Apostle that he breaks out into an impassioned ascription of praise, with which the first (doctrinal) portion of the Epistle is brought to a close.
