Yeshayah 29:13-15

Orthodox Jewish Bible

¹³ Therefore Adonoi says, Forasmuch as this people draw near Me with their peh, and with their sfatayim do honor Me, but have removed their lev far from Me, and their fear toward Me is mitzvat anashim melummadah (human commandments taught by rote);

¹⁴ Therefore, hineni, I will again do an astonishing work among this people, even a marvellous work and a peleh (wonder); for the chochmah of their chachamim shall perish, and the binah (understanding) of their sages shall vanish.

¹⁵ Hoy (woe, doom) unto them that go to great depths to hide their etzah (plan) from Hashem, and their ma’asim are in the dark, and they say, Who seeth us? And who knoweth us?
