a Bible passage
19For it is written,
“I will destroy the wisdom of the wise,
and the discernment of the discerning I will thwart.”
19. I will destroy—slightly altered from the Septuagint, Isa 29:14. The Hebrew is, "The wisdom of the wise shall perish, and the understanding of their prudent men shall be hid." Paul by inspiration gives the sense of the Spirit, by making God the cause of their wisdom perishing, &c., "I will destroy," &c.
understanding of the prudent—literally, "of the understanding ones."
