Facebook CEO Mark Zuckerberg posted yesterday a demonstration of himself blowing a shofar for Rosh Hashanah, reported Yisrael Hayom. The video became popular and received many comments in short order.

Zuckerberg uploaded the video for Rosh Hashanah under the caption "Shana tova and a sweet new year!". He explained is was the Jewish New Year to a Muslim who wondered about the holiday's meaning.

Zuckerberg does not dwell on his Jewish origins, and the last time he mentioned them on his Facebook account was about a year ago, when he shared Sabbath eve experiences and photos with his folloowers. He and his daughter Max were seen next to Shabbat candles with two pictures of Shabbat challah bread baked in the home oven.

Zuckerberg told the social network that "her great-great-grandfather, Max, received the oven after our family emigrated here, and it has been handed down from generation to generation in our family ever since."
