• Hiligaynon: “I am also against those prophets who only speak of their own message and say that I am the one as-it-is-told have-spoken. They tell dreams that is not true, and they lead-astray my people of their lies which they say in-rush. I have- not [intensifier] -sent them or commanded to speak. Therefore they could never give any benefit to the people. I, the LORD, (am) the-(one) saying this.” (Source: Hiligaynon Back Translation)
