The Lamb of the Tribe of Judah

In the old testament, jesus is depicted as a lamb. The odds of him being a key figure in biblical prophecy are vanishingly small. David caresh was using a set of really bad interpretive principles. He assumed that revelation was talking about things that would happen in his own location and time. It's obvious to everyone, even non christian scholars, that the lamb is jesus,. So how could david karesh think it was him?
