Exodus 3: 2 And the angel of the Lord appeared to him in a flame of fire out of the midst of a bush. He looked, and behold, the bush was burning, yet it was not consumed… God called to him out of the bush, “Moses, Moses!”

And he said, “Here I am.”

5 Then he said, “Do not come near; take your sandals off your feet, for the place on which you are standing is holy ground.” 6 And he said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.”

And Moses hid his face, for he was afraid to look at God.

Numbers 9: 15 On the day that the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony. And at evening it was over the tabernacle like the appearance of fire until morning.

16 So it was always: the cloud covered it by day and the appearance of fire by night.

Ezekiel 1:4 As I looked, behold, a stormy wind came out of the north, and a great cloud, with brightness around it, and fire flashing forth continually, and in the midst of the fire, as it were gleaming metal.

Malachi 3:2 But who can endure the day of his coming, and who can stand when he appears?

For he is like a refiner’s fire and like fullers’ soap…

5 “Then I will draw near to you for judgment.

I will be a swift witness against the sorcerers, against the adulterers, against those who swear falsely, against those who oppress the hired worker in his wages, the widow and the fatherless, against those who thrust aside the sojourner, and do not fear me, says the Lord of hosts.

Matthew 13: And his disciples came to him, saying, “Explain to us the parable of the weeds of the field.”

37 He answered, “The one who sows the good seed is the Son of Man.

38 The field is the world, and the good seed is the sons of the kingdom.

The weeds are the sons of the evil one, 39 and the enemy who sowed them is the devil.

The harvest is the end of the age, and the reapers are angels.

40 Just as the weeds are gathered and burned with fire, so will it be at the end of the age.

41 The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers, 42 and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth.

43 Then the righteous will shine like the sun in the kingdom of their Father.

He who has ears, let him hear.

 Mark 1:8 KJV I indeed have baptized you with water:

but he shall baptize you with the Holy Ghost.
