why jewish sit shivah after someone past away?

Who is the Jewish Messiah (Elijah?); what does the old testament say about the jewish messiah and when will it occur?

just sent a question. I am a Jewish "Smith"; maybe you did not get my message; forgot to fill out city(?); got this link from Etz Chaim Congregation, Phila Pa. question was old testament on: Jewish Messiah?

Dear rabbi, I'm in troubled waters at home. My wife a habitual lashon hara speaker, she speaks badly about my parents and her friends and even uses power terms sometimes. I tried many things to make her change the habit and now I'm getting desperate. About 3 months ago I started screaming at her, but even this does not help. I tried reasoning, I gave her books on loshon hara (including Chofetz Chaim), I sent her to lessons on the subject, I told her I don't want her to speak loshon hara, I screamed at her. Nothing and I mean Nothing is working there is not even a slight improvement. I'm really desperate, what more except for maybe hitting her can I do ? Kind regards Rafael
