A wife whose husband died—she can dwell in the houses like she would dwell in them while her husband was alive, she can use the slaves and handmaids, silver and gold vessels, just as she would use them while her husband was alive, for thus he writes for her [in the ketubah]: "You should dwell in my house and be supported from my property any number of days you are a widow in my house."
