Deuteronomio 18:20

Empero el profeta que presumiere hablar palabra en mi nombre, que yo no le haya mandado hablar, ó que hablare en nombre de dioses ajenos, el tal profeta morirá.

But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
