"Your enemies… Your foes… You will burn them up as in a blazing furnace. The LORD will swallow them up in His wrath, and His fire will consume them." - Ps. 21:8-9
What is the final end of God's enemies?
Let's start with some general verses concerning God's enemies.
And My hand takes hold on justice,
I will render vengeance on My adversaries,
And I will repay those who hate Me." Deut. 32:41
As wax melts before the fire,
So let the wicked perish before God." Ps. 68:2

All who do iniquity will be scattered." - Ps. 92:9

He will utter a shout, yes, He will raise a war cry,
He will prevail against His enemies." - Is. 42:13

And like dew which soon disappears,
Like chaff which is blown away from the threshing floor
And like smoke from a chimney." - Hosea 13:3
And I placed you there.
You were on the holy mountain of God;
You walked in the midst of the stones of fire.
You were blameless in your ways
From the day you were created
Until unrighteousness was found in you.
By the abundance of your trade
You were internally filled with violence,
And you sinned;
Therefore I have cast you as profane
From the mountain of God.
And I have destroyed you, O covering cherub,
From the midst of the stones of fire.
Your heart was lifted up because of your beauty;
You corrupted your wisdom by reason of your splendor.
I cast you to the ground;
I put you before kings,
That they may see you.
By the multitude of your iniquities,
In the unrighteousness of your trade
You profaned your sanctuaries.
Therefore I have brought fire from the midst of you;
It has consumed you,
And I have turned you to ashes on the earth
In the eyes of all who see you.
...you have come to a horrible end
and will be no more." - Eze. 28:14-19
And the enemies of the LORD will be like the glory of the pastures,
They vanish—like smoke they vanish away." Ps. 37:20
The hairy crown of him who goes on in his guilty deeds." - Ps. 68:21
Death, the last enemy
From this study, it became clear that God was going to wipe out all enemies: wicked creatures, death, hades, sin and the like... "for our God is a consuming fire" (Heb. 12:29). His mercy and compassion run deep. But even now as "mercy triumphs over judgment" (James 2:13) there is coming a Day of wrath, "a certain fearful expectation of judgment and a fury of fire which will consume the adversaries" (Heb. 10:27).
