Translation of "Confound" in Spanish

When in doubt tell the truth. It will confound your enemies and astound your friends.

Cuando tengas dudas di la verdad. Eso confundirá a tus enemigos y asombrará a tus amigos.

Come ye, therefore, let us go down and there confound their tongue, that they may not understand one another's speech.

"Bajemos, pues, y, una vez allí, confundamos su lenguaje, de modo que no se entiendan entre sí."
