Reply To: How Was Vashti Killed?

Reb Eliezer, even if Vashti was still 19 why would a drunk Achashveirus wait until she’s 20 before beheading her? Is 20 the age of responsibility for non-Jews under Jewish law or under Persian law? If under Jewish law, why would Achashveirus be adhering to Jewish law? Furthermore, under Jewish law the age of responsibility is 13/12.
