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.

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.

I neither learned wisdom,.... Natural wisdom or philosophy, so as to understand the nature of things, and reason about them in a philosophical manner; or political wisdom, so as to know how to govern states, and manage the affairs of kingdoms; or in a lower sphere to transact the affairs of life to any peculiar advantage; he had not a polite or liberal education: or spiritual and evangelical wisdom; that is, not of himself through the mere strength and force of his genius and natural capacity, or of others; he was not the son of a prophet, nor brought up in the schools of the prophets; he did not learn it, nor was he taught it by men; for this is not acquired by human teaching; it is what comes from above, from heaven, and by the revelation of God;
nor have the knowledge of the holy; or "holies" (s); either of holy persons, such knowledge as holy men of God had; or of the holy angels, not of their nature, capacities, influence and operations; nor such as they have: or rather of the holy Persons in the Trinity, Father, Son and Spirit; their nature modes of subsisting, perfections, purposes, and the like; at least not a full and comprehensive one: or of holy things, of the holy Scriptures, and the holy doctrines of them; however, not what is perfect and complete. It may be rendered, "but I have the knowledge of the holy" (t), though he had not the advantage of human literature, nor had ever been under the instructions of men on one account or another, and therefore what he knew, or was about to discourse of, was from God. Some understand this verse and Proverbs 30:2 of Ithiel, or Christ (u), as in the esteem of men, 1-Corinthians 1:23.
(s) "sanctorum", V. L. Pagninus, Montanus, Vatablus, Junius & Tremellius, Piscator, Mercerus, Gejerus, Cocceius, Schultens. (t) "ad cognitionem sanctorum novi", Michaelis; "expers sum humanarnm artium, et divinarum guarus sum", Vatablus in Gejerus. (u) Teelman. Specimen. Explicat. Parabol. p. 391.

I neither learned - I have not been taught in the schools of wisdom. Of the holy - Of the holy prophets. I have not such Divine inspirations as prophets strictly so called have received.
