There is a famous Midrash that Yaakov took a Vav from Eliyahu. This is why their names are spelled אליה & יעקוב They say it has to do with the announcements. What did he take? I.e. what כח was in the Vav? Reference: www.sefaria.org/Rashi_on_Leviticus.26.42.1

The Talmud in Masechet Avodah Zarah 43a states Jews are forbidden from making replicas of items of the temple. My question is, are they issur hanaah?

According to Halacha are Jews obligated to do bedikat chametz before Passover in cars? Or no, is there not an active obligation to search for chametz before Pesach in cars?
