The standard text of havdala includes not only a statement formally acknowledging that Shabbat or Yom Tov has ended, but also a series of distinctions - of things that stand in contrast to one another. This tradition stems from the statement of Rabbi Elazar quoting Rabbi Oshaya that at least three such distinctions are to be included in the havdala blessing, but no more than seven. Rabbi Yehoshua ben Levi comments that ideally the model of the havdala blessing should be distinctions made in the Torah itself.
