I neither learned wisdom - I have never been a scholar in any of those schools of the wise men, nor have the knowledge of the holy, קדשים kedoshim, of the saints or holy persons.

The Septuagint give this a different turn: yeov dedidace me sofian, kai gnwsin agiwn egnwka; "God hath taught me wisdom, and the knowledge of the saints I have known."

This may refer to the patriarchs, prophets, or holy men, that lived before the days of Solomon. That is, the translators might have had these in view.

He found, when he looked within, that all his learning was as nothing. He had heard of God only “by the hearing of the ear” Job 42:5, and now he discovered how little that availed.

The holy - The Holy One. Compare Proverbs 9:10.

Agur speaks of himself as wanting a righteousness, and having done very foolishly. And it becomes us all to have low thoughts of ourselves. He speaks of himself as wanting revelation to guide him in the ways of truth and wisdom. The more enlightened people are, the more they lament their ignorance; the more they pray for clearer, still clearer discoveries of God, and his rich grace in Christ Jesus. In ver. 4, there is a prophetic notice of Him who came down from heaven to be our Instructor and Saviour, and then ascended into heaven to be our Advocate. The Messiah is here spoken of as a Person distinct from the Father, but his name as yet secret. The great Redeemer, in the glories of his providence and grace, cannot be found out to perfection. Had it not been for Christ, the foundations of the earth had sunk under the load of the curse upon the ground, for man's sin. Who, and what is the mighty One that doeth all this? There is not the least ground to suspect anything wanting in the word of God; adding to his words opens the way to errors and corruptions.
