Theophylact of Ohrid, on Rom 11:33

“O the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible are his judgments, and how unsearchable his ways!”

“Reflecting on the dispensations of God from the beginning of the world, on how God arranges the opposite through the opposite and by means of some who are disobedient shows others to be obedient, he came to amazement, thereby confirming that He who so arranges our affairs will assuredly also arrange the future salvation of the Jews. By "riches" he means goodness, the depth of which only brings amazement, and the greatness of which is unknown: for to so enrich the Gentiles is a work of riches. Together with goodness he marvels also at "wisdom," by means of which God governs our life and made wise the ignorant Gentiles, and at "knowledge," by means of which He knows what is profitable for each person. Concerning His ways, he did not say "incomprehensible," but "unsearchable," that is, they cannot even be searched out. "His ways," that is, the methods of His dispensation, not only cannot be comprehended, but cannot even be searched out, that is, one cannot even see a trace of them.”
