What is a metaphor used in Jeff Buckley's Hallelujah? Please help meee.

Question

Well I've heard there was a secret chord 

That David played and it pleased the Lord 

But you don't really care for music, do you? 

Well it goes like this 

The fourth, the fifth, the minor fall and the major lift 

The baffled king composing Hallelujah  

Hallelujah x4 

Well your faith was strong, but you needed proof 

You saw her bathing on the roof 

Her beauty and the moonlight overthrew ya 

She tied you to her kitchen chair 

And she broke your throne and she cut your hair 

And from your lips she drew the Hallelujah 

Hallelujah x4 

But baby I've been here before 

I've seen this room and I've walked this floor 

You know, I used to live alone before I knew ya 

And I've seen your flag on the marble arch 

And love is not a victory march 

It's a cold and it's a broken Hallelujah 

Hallelujah x4 

Well there was a time when you let me know 

What's really going on below 

But now you never show that to me do ya 

But remember when I moved in you 

And the holy dove was moving too 

And every breath we drew was Hallelujah 

Hallelujah x4 

Maybe there's a God above 

But all I've ever learned from love 

Was how to shoot somebody who outdrew ya 

And it's not a cry that you hear at night 

It's not somebody who's seen the light 

It's a cold and it's a broken Hallelujah 

Hallelujah x12 

Hallelujah 

Answer 1

The allusion in the opening lines is to the biblical story of David and Bathsheba, which you should read (or at least read about).

Your question, then, could be answered in a couple of ways. In the largest sense, the writer is comparing his relationship to that of the biblical king and the woman he lusted after.

If you want to focus on details instead, the religious phrase "hallelujah" (praise god) would have somewhat similar meaning if the scene were shifted into a bedroom, if you get my drift.
