The Temple Institute and Boneh Israel made a huge step towards reinstating the Temple service on Thursday when five red heifers landed at Ben Gurion International Airport.
The red heifer was the main component in the Biblically mandated process of ritual purification for impurity that results from proximity or contact with a dead body. Because the elements needed for this ceremony have been lacking since the destruction of the Second Temple, all Jews today are considered ritually impure, thereby preventing the return of the Temple service.
The Temple Institute launched its Red Heifer program about a decade ago, led by Rabbi Azariah Ariel. But even in Temple times, an animal that fulfilled the Biblical requirements was exceedingly rare. Failing to produce a suitable candidate from ranchers in Israel, The Temple Institute began investigating alternative sources for a red heifer.
