The Torah in its abundant concern for the poor in our society put in place many Mitzvos ensuring we give parts of our crop to the needy.  Whats strange is one of those agricultural Mitzvos is Ma’aser Sheni which commands us to take our crop to the city of Yerushalayim and simply eat it there.  We don’t give anything to the poor.  We didn’t sing any song.  We didn’t chant any spiritual chant.  We just showed up, ate and returned.  What was the point of this Mitzvah?  What are we accomplishing?  The answer might surprise you.
