Following are a number of back-translations as well as a sample translation for translators of Jeremiah 25:30:

• Kupsabiny: “Go and announce to those people everything that I God am saying. You should tell these people,
  ’God will roar from heaven/up,
  and thunder from the top of the world,
  he shall roar to his people.
  He will roar like people who squeeze grapes,
  shouting to all the people who live in the world/land.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘Jeremias, tell them all that I said, and tell them: ‘The LORD will-roar from heaven; his voice will-thunder from his holy place-of-dwelling. He will-roar loudly against his people. He will-shout against all who live on the earth like a man who shouts while treading the grapes.” (Source: Hiligaynon Back Translation)
• English: “Now tell them all those things that I have said, and also say this to them:
  ‘Yahweh will shout to them from his holy dwelling in heaven
  and it will sound like the roar of a lion.
  He will shout like people shout when they are treading on grapes to make juice for wine;
  he will shout to everyone on the earth.” (Source: Translation for Translators)
