I neither learned wisdom, nor have the knowledge of the holy.
I nether learned wisdom, nor have (know) the knowledge of the holy - naturally. As in Proverbs 30:2 he disclaimed original knowledge, so in this verse he disclaims humanly acquired knowledge of the deep mysteries of God. A man must first "become a fool that he may be wise" (1 Corinthians 3:18). So long as he thinks he knows, he is unfit to be a vessel of the knowledge received from above (1 Corinthians 8:2; Isaiah 6:5). "The holy" (note, Proverbs 9:10), either all that concerns the holy God, or the holy God; qªdoshiym (H6918). Plural, as 'Elohiym (H430).
