Again..my music pioneer stories..

Hello guyz..! May u all have a better life day by day...
Now my blog tells a short story about one of my favourite song came from my fluencies band (METALLICA!) called ‘CREEPING DEATH’. The content of the lyric amused me the most. Yeah, the melody sound's heavy, thrash metal & stuff like that. But it just occurred to me from the lyric itself that EGYPT alwayz got a hidden classic story that fascinated the adventurer to book it. Do me a favor. Can someone please HELP ME translate the lyric in a form of summary? Juz asking for some share-partner guidance hehe

"Creeping Death" is a song by Metallica and is the seventh track on their album Ride the Lightning. It is written from the point of view of the Plague of the Firstborn (Exodus 12:29), that is, the Destroyer. The song is 6 minutes and 36 seconds long. "Creeping Death" is also one of Metallica's most frequently played songs, and stands as a classic example of the band's thrash style, albeit slower than the Kill 'Em All material. The middle section, based around ominous chants of "Die!" set to a perilous phrygian-mode chord progression, is a fan participation staple during Metallica shows.



CREEPING DEATH
Slaves
Hebrews born to serve, to the pharaoh
Heed
To his every word, live in fear
Faith
Of the unknown one, the deliverer
Wait
Something must be done, four hundred years

So let it be written
So let it be done
I'm sent here by the chosen one
So let it be written
So let it be done
To kill the first born pharaoh's son
I'm creeping death

Now
Let my people go, land of Goshen
Go
I will be with thee, bush of fire
Blood
Running red and strong down the Nile
Plague
Darkness three days long, hail to fire

So let it be written
So let it be done
I'm sent here by the chosen one
So let it be written
So let it be done
To kill the first born pharaoh's son
I'm creeping death

Die by my hand
I creep across the land
Killing first-born man
Die by my hand
I creep across the land
Killing first-born man

I
Rule the midnight air, the destroyer
Born
I shall soon be there, deadly mass
I
Creep the steps and floor, final darkness
Blood
Lambs blood painted door, I shall pass

So let it be written
So let it be done
I'm sent here by the chosen one
So let it be written
So let it be done
To kill the first born pharaoh's son
I'm creeping death
