Then the Lord said, “Because this people approaches Me with their words and honors Me with their lips, but their heart is far away from Me, and their reverence for Me consists of the commandment of men that is taught. Therefore behold, I will once again deal marvelously with this people, wondrously marvelous; and the wisdom of their wise men will perish, and the understanding of their men who have understanding will be concealed.”

Isaiah 29:13-14 (NASB).
