For the phrase “The wisdom of their wise shall perish, and the discernment of the discerning shall be hidden,” see 1 Corinthians 1:19.

Note that this quote in the New Testament is not taken from the Hebrew Bible but from the Greek Septuagint (LXX) which translates into English as “I will (…) destroy the wisdom
of the wise, and the discernment of the discerning I will hide” (Translation by NETS — for the Greek version see the title’s tooltip)
