There is also their power to hurt the world with all kinds of plagues/tormentings, whenever they want to do it.” (Source: Uma Back Translation)
• Yakan: “They have authority to shut the sky so that it will not rain as long as they make-known God’s message.

• Western Bukidnon Manobo: “They will be given power that they might be able to hinder the clouds so that it will not rain during the time they are preaching the Word of God. And they will also have power so that they might turn to blood the water in the springs.
