Would you pay $18 to help produce an immaculate cow? If so, Jerusalemâ??s Temple Institute, dedicated to doing â??all in our limited power to bring about the building of the Holy Temple in our time,â? has just the crowdfunding campaign for you: Launched earlier this month, it hopes to raise $125,000 in order to implant the frozen embryos of Red Angus cattleâ??a hardy breed popular everywhere from Australia to the American Westâ??in Israeli cows, introducing the animals to the Holy Land in the hope that the herd soon produces an unblemished red heifer.
