'Aloud' in the Bible

At noon Elijah mocked them, saying, “Cry out with a loud voice, for he is a god; either he is occupied, or he is out [at the moment], or he is on a journey. Perhaps he is asleep and must be awakened!”

So they cried out with a loud voice [to get Baal’s attention] and cut themselves with swords and lances in accordance with their custom, until the blood flowed out on them.
