Quote:But a difference is not necessarily a contradiction
Oh cut the shit. In this case it is a correction, not even a contradiction.
97% of "mark" is copied by "matty." Was he stupid or just a plagiarizer?
In this case he read what mark said, realized that it was absurd based on his own knowledge of the area and tried (badly) to correct it. It is generally conceded that matty is the most "jewish" of the gospels which indicates a far greater understanding of the region than the other two synoptics had.
