The Hall of Isaac at the Tombs of the Patriarchs in Hebron, West Bank, was filled with thousands of Jewish worshippers — men and women — on April 23 in the intermediate days of Passover. Most came for a special mass singing event, where together they sang during morning prayers the verse “What will I return to the Lord,” from the book of Psalms.
Documented by drone cameras, amplified and accompanied by music, the event is part of the mass singing trend, Koolulam — which is a wordplay on "koolulu," the traditional celebratory ululation of Middle Eastern and North African Jews, and "koolam," which means "everyone" in Hebrew. The trend is taking Israel by storm and was certainly reflected in the mass singing at the Tombs of the Patriarchs.
