Ket 62a
This is as it is related about Rav Reḥumi, who would commonly study before Rava in Meḥoza: He was accustomed to come back to his home every year on the eve of Yom Kippur. One day he was particularly engrossed in the halakha he was studying, and so he remained in the study hall and did not go home. His wife was expecting him that day and continually said to herself: Now he is coming, now he is coming. But in the end, he did not come. She was distressed by this and a tear fell from her eye. At that exact moment, Rav Reḥumi was sitting on the roof. The roof collapsed under him and he died. This teaches how much one must be careful, as he was punished severely for causing anguish to his wife, even inadvertently.
