'Louder' in the Bible

When the sound of the horn grew louder and louder, Moses was speaking and God was answering him with a voice.

At noon Elijah mocked them, "Yell louder! After all, he is a god; he may be deep in thought, or perhaps he stepped out for a moment or has taken a trip. Perhaps he is sleeping and needs to be awakened."

So they yelled louder and, in accordance with their prescribed ritual, mutilated themselves with swords and spears until their bodies were covered with blood.
