Isaiah 29:13-15

13So Adonai says, “Since these people draw near with their mouths and honor Me with their lips, yet their hearts are far from Me, and their fear of Me is a mitzvah taught by men.

14Therefore, behold, once more I will do a marvelous work among this people— a marvel and a wonder— so the wisdom of their wise will perish, and the discernment of their discerning will be concealed.”

15Oy , those who go to great depths to hide their plans from Adonai! Their works are in the dark. They say, “Who sees us? Who knows us?”
