Solomon wrote much of Proverbs.
He also wrote a lot of poetry and sayings.
From what I understand, only a very small part of all that Solomon wrote ended up in the Bible.
The first verse goes like this:
Song of Solomon 1:1 The song of songs, which is Solomon's.
In Hebrew, the saying, song of songs, is like saying the best of songs. Just as in Isaiah 6, the angels didn't just cry out, "holy is the Lord." They cried out "holy, holy, holy is the LORD God Almighty." One holy simply was not enough. God most certainly is three times holy. So saying that Song of Solomon is just a song, is not enough. It is the Song of Songs. It is the best.
Now, I don't know if SOS (Song of Solomon) is the best song written by Solomon, or if it is the best song written in it's day, or if it is the best song written ever. But at the very least, we should get that this was/is one awesome song, even if we don't understand every part of it.
Funny thing about this best of songs.
It was banned by certain Puritan groups in at least one of the original 13 colonies. Seems SOS wasn't just a bit racy for this 21st century gal. It was also a bit much for some of our earlier settlers.
And I had also heard that some Jewish sects did not allow their members to study SOS until they turned 30. They also thought it was a bit much, at least for the younger generation.
So it is safe to say that SOS is a controversial book.
Yet we must never forget that it is the Best of Songs and is worthy of our attention.
