Thou shalt not have in thy bag divers weights
Or, "a stone and a stone" F25; it being usual, in those times and countries, to have their weights of stone, as it was formerly with us here; we still say, that such a commodity is worth so much per stone, a stone being of such a weight; now these were not to be different:
a great and a small;
great weights, to buy with them, and small weights, to sell with them, as the Targum of Jonathan paraphrases it.
