'Shower' in the Bible

Now Elijah said to Ahab, “Go up, eat and drink; for there is the sound of the roar of a heavy shower.”

It came about at the seventh time, that he said, “Behold, a cloud as small as a man’s hand is coming up from the sea.” And he said, “Go up, say to Ahab, ‘Prepare your chariot and go down, so that the heavy shower does not stop you.’”

In a little while the sky grew black with clouds and wind, and there was a heavy shower. And Ahab rode and went to Jezreel.
