Therefore I will again confound these people with wonder upon wonder. The wisdom of the wise will vanish, and the intelligence of the intelligent will be hidden.”
KJV
Therefore, behold, I will proceed to do a marvellous work among this people, [even] a marvellous work and a wonder: for the wisdom of their wise [men] shall perish, and the understanding of their prudent [men] shall be hid.
ASV
