What's more important - the first half of the Ten Commandments or the second set? Many think that the first half is more significant, because it deals with our relationship with G-d and the second set deals with our relationship with man. However, It is precisely for this reason that the second set could take precedence. The Mitzvah of sending away the mother bird before taking away the chicks or eggs from the nest, leaves us with an important lesson. G-d wants us to be sensitive to others, even when working on holy projects.
