1 Corinthians 1:19
For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
1:19. As he often did, Paul illustrated his point by an example of Israel who, following humanly wise counsel, formed an alliance with Egypt as a defense against Assyria, when in fact only the miraculous intervention of God was able to save them (cf. Isa. 29:14; 2 Kings 18:17-19:37).
