Our Jewish relationship with law is complex. Many of the laws in our Torah are designed for a people living autonomously in ancient times and therefore have, for most of the time they’ve existed, been inapplicable or impracticable or preempted by the laws of whatever country we’re living in. And yet we still accord them an odd place of honor in our spiritual life. We walk around judging ourselves to be “bad Jews” when we don’t follow some Jewish law that we’re still somehow conversant in. What is it that makes us feel a little something extra about this body of law?

So why “up and down” the ladder and not “down and up”? The rabbis went crazy with this one. They understood "up and down" to be sequential, and they struggled to figure out why angels would originate on earth and not in heaven. Some of their answers were practical. The angels, like police officers or newspaper boys, had regular beats. At the end of your land, your accompanying angel loses jurisdiction. So your angel ascends again to heaven. Who descends? The angel who will accompany you on the next leg of your journey.
