Things get wild in Song of Songs, in large part thanks to the crazy animal imagery:
Yeah, the Bible is pretty racy when you give its metaphors a shot.
Sometimes, though, the metaphors don't translate very well into our generation. Remember that line from Chapter 4 when the groom says, "Your hair is like a flock of goats, moving down the slopes of Gilead" (4:1)? Not exactly the best compliment to give in our world today, right? But here's deal. Metaphors like these can tell us a lot about life in the ancient world. Why would you say something like that unless it would produce a blush and a smile?
Let's do our best to interpret that metaphor, ancient-style. Think about looking at a far off flock of goats, grazing on the slopes. All of the animals will seem like one mass, right? And when they move, it'll probably look pretty cool.
Still with us? Okay. What job would you have to have to be really familiar with that image? Yep, shepherding. And there you have it: our guy is a shepherd. (Jump on down to "Shepherds and Flocks" for more on this.)
