John Lightfoot on Mark 11:16

[And would not suffer that any man should carry any vessel through the Temple.] "What is the reverence of the Temple? That none go into the Mountain of the Temple" [or the Court of the Gentiles] "with his staff, and his shoes, with is purse, and dust upon his feet: and that none make it his common thoroughfare, nor make it a place of spitting."

The same thing is ordered concerning a synagogue; yea, concerning a synagogue that is now laid waste, much more of one that flourisheth: "A synagogue now laid waste, let not men make it a common passage." And "his disciples asked R. Eleazar Ben Shammua, Whence hast thou lived so long? He answered, I never made a synagogue a common thoroughfare."

It is therefore forbid by the masters, that the court of the Temple be not made a passage for a shorter way. And was not this bridle sufficient wherewith all might be kept back from carrying vessels through the Temple? But the 'castle of Antonia' joined to the court; and there were shops in the Court of the Gentiles where many things were sold; and that profane vessels were brought hither is scarcely to be denied. And these vessels might be said to be carried through the Temple; although those that carried them went not through the whole Temple.
