Because of a performance in front of a “mixed audience” of men and women, the singer Erez Yechiel was lashed 39 times by rabbis after a ruling by a self-described rabbinic court in August 2010, reported Jerusalem Post

Rabbi Amnon Yitzhak, founder of the Shofar organization which is aimed at bringing Jews “back to religion” (hazara betshuva), has made it his recent mission to fight against musical performances for both men and women.

His “judicial panel,” with Rabbi Ben Zion Mutsafi and another member, sentenced Erez Yechiel to 39 lashes in order to “rid him of his sins.”

In a video clip of the court posted on the Shofar web site, Ben Zion said that those who make others sin (mahtiei rabim), such as artists who make men and women attend performances or dance together, have no place in the world to come.

He displayed a leather strip he said was made by his father from ass and bull skin, with which Yechiel was to have been whipped.

Yechiel, who said, “I accept upon myself the lashing for my sins,” was ordered to stand by a wooden poll with his head facing north (“from whence the evil inclination comes”), his hands tied with a azure-colored rope (“a symbol of mercy”).
