Isaías 33

You will not look upon a shameless people, a people of exalted words. For you are not able to understand the dissertation of a tongue in which there is no wisdom.

No verás á aquel pueblo espantable, pueblo de lengua oscura de entender, de lengua tartamuda que no comprendas.

Thou shalt not see a fierce people, a people of a deeper speech than thou canst perceive; of a stammering tongue, that thou canst not understand.

You will no longer see the fierce people, a people of a deep speech that you can’t comprehend, with a strange language that you can’t understand.
