Isaías 33
Young's Literal Translation
19The strong people thou seest not, A people deeper of lip than to be understood, Of a scorned tongue, there is no understanding.
Reina-Valera 1909
19No verás á aquel pueblo espantable, pueblo de lengua oscura de entender, de lengua tartamuda que no comprendas.
King James Version
19Thou 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.
World English Bible
19You 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.
