The More the “Marry”er?!
How did Yaakov have more than one wife? Is this permissible according to Jewish law?!
Well, according to the Torah, there is absolutely nothing wrong with that. Nowadays however, this would never happen. More than 1,000 years ago, the great Rabbeinu Gershom of Germany issued a decree stating that it is forbidden to have more than one wife at a time. He must divorce one wife before marrying another.
BTW: Rabbeinu Gershom instituted other laws which became known as Cherem D’Rabbeinu Gershom (The Prohibitions of Rabbi Gershom). A famous one is the prohibition against opening and reading a letter addressed to someone else. Nowadays this would include reading someone else’s email.
