text: jewish people...if sacrifice was only allowed in the temple..what about the sacrifice of abraham? didn't abraham sacrifice on a mountain isnt that where god provided himself a lamb? yes, you are right.  and, it was on mt. moriah.  this is where the temple was later built.  it was all the same place.  the rock abraham put his son on is the rock in the now present dome of the rock.  interesting question---------and an unusual one!  that is nice.
