This thing called marriage
In Judaism, only a person who is married according to Torah law is eligible to give or receive a divorce. Marriage in the Jewish tradition is a very ancient practice. The first couple to ever get married was Adam and Eve over 5,000 years ago. Marriage is a mitzvah, and seven blessings are recited for it under the chuppah. While divorce is also a very ancient rite that is mentioned in the Torah, it is not exactly correct to call it a mitzvah. In fact, no blessing is recited over it, because it is an unfortunate occurrence. There have always been unhappy marriages, and yet until recently, divorce used to be relatively unknown in the Jewish community.
