This week's Torah portion begins with "And these are the laws..."and goes on to relate laws involving financial matters, damages, and the like.
Why start a new section with the word "And"?
Our sages explain that this is to show that these laws are equal to the ones mentioned in the previous section at the Giving of the Torah at Mount Sinai. That just as those were clearly G-dly, so, too, are the everyday laws mentioned here.
The lesson for us is that while there are different types of Mitzvot in the Torah, some that are easy to appreciate and understand and others that are beyond human understanding and clearly G-dly in origin --
Nevertheless, we should realize that all of them really emerge from the same lofty place, the Wisdom of the Creator. It is merely that G-d chose to make certain ones appear logical and others beyond human logic. But essentially, all Mitzvot -- even the openly rational ones -- emerge from the infinite depths of G-d's Wisdom.
