Ver. 13. Thou shalt not have in thy bag divers weights— In the margin of our Bibles, a stone and a stone: so, a heart and a heart, meaneth a double and deceitful heart; 1 Chronicles 12:33. The same mode of expression is used in the 14th verse. This law teaches them to be so far from practising deceit, that they were not even to retain the instruments of it; not to have a great weight to buy with, and a small one to sell with: a method of cheating, it is to be feared, but too common in our days. See on Leviticus 19:35.
