Thou shalt not have in thy bag divers weights, a great and a small.
Thou shalt not have ... divers weights, х 'eben (H68) waa'aaben (H68)] - 'a stone and a stone' [Septuagint, stathmion kai stathmion]; a just and false, or a light and heavy one. Weights were anciently made of stone; and the facility for procuring stones apparently, though not exactly similar, gave much occasion to fraud (Leviticus 19:31; Proverbs 16:11; Proverbs 20:10; Micah 6:11).
Bag - the leather pouch in which the weights were kept. Stones are frequently used still by Eastern shopkeepers and traders, who take them out of the bag and put them in the balance. The man who is not cheated by the trader and his bag of divers weights must be blessed with more acuteness than most of his fellows (Roberts, 'Oriental Illustrations,' in hoc loco).
