Prayer is apparently becoming less meaningful to many Orthodox Jews, as well as to Jews in general, but a pioneer program being tested in a handful of yeshiva high schools — including Kohelet Yeshiva High School in Merion Station — is hoping to reverse that. An organization called Legacy 613 (the 613 references the number of mitzvot in the Torah) is behind the program, which was launched in the 2016-17 school year.
