'Rain' in the Bible

Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now.

Moses went out of the city from Pharaoh, and spread abroad his hands to Yahweh; and the thunders and hail ceased, and the rain was not poured on the earth.

When Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants.

Then Yahweh said to Moses, "Behold, I will rain bread from the sky for you, and the people shall go out and gather a day's portion every day, that I may test them, whether they will walk in my law, or not.
