The prophets are poetry, but what they do is search for meaning in the law. They view the law mystically, like it is a map or microcosm of the world. This is because it is a system for living in the world. As a map of the world it should hold secrets. The prophets, then, view the law similarly to the way that ancient astronomers try to read the stars. The prophets, however, have much better luck since the law actually does represent a workable and intimate living system while the stars are just random objects in the sky.
The bible is written to lawyers. The law is the center, but the center of that is the covenant between people, which we ignorantly call 'The LORD'. (my opinion) I view the LORD as I view scripture or as I view the holy spirit, an emanation of the divine but not the divine itself. Its like a piece of a hologram, containing the entire picture that the hologram does but not the actual thing and not the most detail. Still, you can examine a piece of a hologram with a magnifying glass to get some more detail. Thus it makes sense to examine the ways of the LORD very closely. Everything in the bible that has to do with fellowship and avoiding violence is meant to be taken very seriously and is about the ways of the LORD. Everything else is dealing with these things, tangent to them, celebrating them, interpreting them, finding out about them. As some have stated the greatest two commands are to love the covenant and to love your neighbor. This sums up the law and the prophets.
What is not true: superstitions such as the belief that putting ink onto goats will make them bear spotted young. This does not work, ever; nor would anyone in any age believe that it would. The unbelievable and obviously wrong passage is included on purpose to let you know something: that the story is not the point.
