Numbers 21:6

Num 21:6 And the LORD sent fiery serpents among the people, and they bit the people; and much people of Israel died.

Ver. 6. Fiery serpents. ] Heb., Seraphim; from their burning heat, whereby these ungrateful Israelites, that causelessly cried out of thirst, had somewhat given them to cry for. Their tongues, so full of deadly poison, and set on fire from hell, are now parched and scorched with venomous heat and torments, the likest hell of any other. These serpents are here called seraphims: that old serpent the devil can transform himself into an angel of light.
