Isaiah 29:13-15

New Revised Standard Version, Anglicised

¹³ The Lord said:
Because these people draw near with their mouths
    and honour 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.

¹⁵ Ha! You who hide a plan too deep for the Lord,
    whose deeds are in the dark,
    and who say, ‘Who sees us? Who knows us?’
