A married woman acquires herself back through death of her husband. Why?
- Husband
caused the prohibition, and he also removes it? No, because she is
still forbidden to marry his son from the previous marriage or his
father.
- A widow is forbidden to the Chief Priest, so she must
be allowed to marry everyone else? No, perhaps she would still be
transgressing a positive commandment.
- When Jewish soldiers went
to war, “And whichever man betrothed a wife and did not yet take her,
let him return, lest he dies in battle and another man takes her” - is
a valid proof.
