'Rain' in the Bible

hear this: tomorrow about this time I will send a very heavy and dreadful hail, such as has not been seen in Egypt from the day it was founded until now.

So Moses left the city and Pharaoh, and stretched out his hands to the Lord; then the thunder and hail ceased, and rain no longer poured on the earth.

But when Pharaoh saw that the rain and the hail and the thunder had ceased, he sinned again and hardened his heart, both he and his servants.

Then the Lord said to Moses, “Behold, I will cause bread to rain from heaven for you; the people shall go out and gather a day’s portion every day, so that I may test them [to determine] whether or not they will walk [obediently] in My instruction (law).
