Daily Quote
The location of the Altar [in the Holy Temple in Jerusalem] is very exactly defined, and is never to be changed... It is a tradition that the place where David and Solomon built the Altar on the threshing floor of Arona, is the very place where Abraham built an altar and bound Isaac upon it; this is where Noah built [an altar] when he came out from the ark; this is where Cain and Abel brought their offerings; this is where Adam the First Man offered a korban when he was created -- and it is from [the earth of] this place that he was created
  –Maimonides (Mishneh Torah, Laws of the Holy Temple, ch. 2)
