פרשת משפטים

This is what I learned last week: The מצווה not to wrong a stranger (גר) appears 36 times in the Torah, more than any other מצווה. Just so happens that 36 is also the number of the ל"ו צדיקים. According to Jewish tradition, were it not for these 36 righteous people in the world, the world would come to an end. Not sure what to make of that, but I find it very interesting.
