Isaiah 29:13-14 New Revised Standard Version (NRSV)
13 The Lord said:
Because these people draw near with their mouths
and honor me with their lips,
while their hearts are far from me,
and their worship of me is a human commandment learned by rote;
14 so I will again do
amazing things with this people,
shocking and amazing.
The wisdom of their wise shall perish,
and the discernment of the discerning shall be hidden.
