ok.. Red cow.. my bad. https://www.thesun.co.uk/news/7217719/bible-prophecy-apocalypse-firs-red-heifer-born-israel/ What is a red heifer? The red heifer (also known as the red cow) was a cow brought to priests for sacrifice in the Hebrew Bible. Jewish and Christian fundamentalists believe that once a red heifer is born in Israel they will be able to rebuild the Third Temple on the Temple Mount in Jerusalem. But in order to do this, they would have to demolish what stands on the hill today – the Dome of the Rock, an Islamic holy temple. In mainstream Orthodox Judaism, once the Temple is rebuilt the world will welcome the coming of the Jewish Messiah. Why does the bible say they trigger Armageddon? Some theologians say the building of the Third Temple is linked to “Judgement Day” or the “end of times”.
