daf bit: Ketuvot 103
The mishna teaches: should a widow say "I have no desire to move from
my husband's house", the heirs cannot tell her to go back to her
father's house, even if they promise to pay her maintenance. Rather,
they must maintain her in her husband's house. The gemara adds that
she may use not only her husband's house but also his bondsmen,
the silver and gold utensils, and the furnishings, just as during his
lifetime. (103a)
