And Elijah said to Ahab, “Get up, eat and drink; for there is the sound of abundance of rain.” Bible

“there is the sound.” At this point there was not even a cloud in the sky, as we learn a couple of verses later (1 Kings 18:43), but God showed Elijah there was going to be an abundance of rain by making him hear the sound. This is audible revelation; revelation hearing.
