Rabbi
Eliezer validated a Get with a condition "You are permitted to marry
any man but so-and-so." Rabbi Eliezer’s learning was supreme, but after
his death many Rabbis got together to disprove this teaching of his.
However, all but one of their rebuttals had potential flaws.
The
undisputable proof came from Rabbi Elazar ben Azaria. He deduced the
requirement of complete severance from the term that the Torah used,
"Kritut," as opposed to a possible shorter word "Karet." This,
according to Rabbi Elazar Ben Azaria, teaches that temporary conditions
in the Get are valid, but permanent are not.
