If you look at Isaiah 14:4 you'll see that it gives instructions for the correct use of these verses. That is, it says,Metaphor or Literal - what do you think?
Isaiah 14:12-15 New King James Version (NKJV)
“How you are fallen from heaven,
O Lucifer, son of the morning!
How you are cut down to the ground,
You who weakened the nations!
For you have said in your heart:
‘I will ascend into heaven,
I will exalt my throne above the stars of God;
I will also sit on the mount of the congregation
On the farthest sides of the north;
I will ascend above the heights of the clouds,
I will be like the Most High.’
Yet you shall be brought down to Sheol,
To the lowest depths of the Pit.
"You will take up this taunt against the King of Babylon". It's simply a gloat against someone you don't like, who's come to grief. Michael Cohen might suit as a parallel.
Same thing: For the instructions, consult Ezekiel 18:1 ─ "Say to the prince of Tyre, Thus says the Lord". Think of razzing, say, Paul Manafort.Ezekiel 28:14-16 New King James Version (NKJV)
“You were the anointed cherub who covers;
I established you;
You were on the holy mountain of God;
You walked back and forth in the midst of fiery stones.
You were perfect in your ways from the day you were created,
Till iniquity was found in you.
“By the abundance of your trading
You became filled with violence within,
And you sinned;
Therefore I cast you as a profane thing
Out of the mountain of God;
And I destroyed you, O covering cherub,
From the midst of the fiery stones.
