Psalms 104:4

"And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire."

"And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and parted them both asunder; and Elijah went up by a whirlwind into heaven."

"And Elisha prayed, and said, LORD, I pray thee, open his eyes, that he may see. And the LORD opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha."

"Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?"

"Fire, and hail; snow, and vapour; stormy wind fulfilling his word:"

"As for the likeness of the living creatures, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning."

"For the Sadducees say that there is no resurrection, neither angel, nor spirit: but the Pharisees confess both."
