On the day that the tabernacle was set up, the cloud covered the tabernacle -- the tent of the testimony -- and from evening until morning there was a fiery appearance over the tabernacle.

This is the way it used to be continually: The cloud would cover it by day, and there was a fiery appearance by night.

And Jehovah sent fiery serpents among the people, and they bit the people. And many people of Israel died.

And Jehovah said to Moses, Make a fiery serpent and set it on a pole. And it shall be when everyone that is bitten, when he looks upon it, he shall live.
