"and she shall go and she may be to another man": She should not marry in his (the first's) neighborhood.
"another man": Scripture calls him "another," (demonstrating that he is not on a par [morally] with the first, the first having banished "a thing of nakedness" from his home; the second, having admitted her.)
(Ibid. 3) "And if the last man hate her": Scripture apprises us that he is destined to hate her.
"or if the last man die": Scripture apprises us that she is destined to bury him.
If a divorcée (from the second husband) is mentioned (as forbidden to the first,), why mention a widow (as being forbidden to him)? For a divorcée is forbidden to the levir (her second husband's brother [in the event of her second husband's dying without children]) whereas a widow is permitted to the levir (in the above instance).
