Song

I have to say, of all the books of the bible, I have the most trouble with the Song of Solomon. I get that it is supposed to be a picture of God's love for us, but at times it is a bit odd. I found it very hard work to read this book! This part I liked:

2:11 See! The winter is past;
the rains are over and gone.

12 Flowers appear on the earth;
the season of singing has come,
the cooing of doves
is heard in our land.

This part I had a bit of trouble with:

5: 2 I slept but my heart was awake.
Listen! My lover is knocking:
"Open to me, my sister, my darling,
my dove, my flawless one.
My head is drenched with dew,
my hair with the dampness of the night."

3 I have taken off my robe—
must I put it on again?
I have washed my feet—
must I soil them again?

4 My lover thrust his hand through the latch-opening;
my heart began to pound for him.

5 I arose to open for my lover,
and my hands dripped with myrrh,
my fingers with flowing myrrh,
on the handles of the lock.

6 I opened for my lover,
but my lover had left; he was gone.
My heart sank at his departure. [a]
I looked for him but did not find him.
I called him but he did not answer.

7 The watchmen found me
as they made their rounds in the city.
They beat me, they bruised me;
they took away my cloak,
those watchmen of the walls!

It puzzled me that the Jesus/God character would knock and then leave, as there is a scripture in the NT about knocking and it being opened, etc.
In http://www.ldolphin.org/ssong.shtml they suggest that the passage talks about Jesus at Gethsemane- how he wants the disciples there, but they waver and then He is gone. Then they have to defend their faith.
When God is hard to find, I generally find that the problem is me, not Him. That He wants to be found. But that watchmen beat you up all the time, yeah, I understand that!
