Lag ba-ʿOmer, also spelled Lag Bʾomer or Lag Be-omer, minor Jewish observance falling on the 33rd day in the period of the counting of the ʿomer (“barley sheaves”); on this day semi-mourning ceases and weddings are allowed. The origin of the festival is obscure. Among many traditions, one holds that manna first fell from heaven on this day; another tradition claims that a plague that raged among the followers of Rabbi Akiva ben Yosef during ʿomer ceased on this day. In Meron in Upper Galilee, Israel, Orthodox Jews by the thousands make a joyous pilgrimage to the burial site of the great rabbi Shimon bar Yochai, and young children receive their first haircuts as part of a popular celebration that includes playing with bows and arrows (symbols of the rainbow) and dancing around a bonfire at night.
