Isaiah 29:13-15

Amplified Bible

“Because this nation approaches [Me only] with their words
And honors Me [only] with their lip service,
But they remove their hearts far from Me,
And their reverence for Me is a tradition that is learned by rote [without any regard for its meaning],
¹⁴ 
Therefore, listen carefully, I will again do marvelous and amazing things with this people, wonderful and astonishing things;
And the wisdom of their wise men will perish,
And the understanding of their discerning men will be hidden.”

¹⁵ 
Woe (judgment is coming) to those who [try to] deeply hide their plans from the Lord,
Whose deeds are done in a dark place,
And who say, “Who sees us?” or “Who knows us?”
