Zechariah 12:3

A burdensome stone. — In lifting which the builders might lacerate themselves: meaning that those who should endeavour to build Jerusalem into the fabric of their own dominion should injure themselves in the attempt. But some (as Jerome) suppose the figure to be borrowed from some such athletic sport as “lifting the weight;” while others take the expression in a more general sense, as referring merely to a weight which is too heavy to be borne.
