A just weight and balance are the LORD's: all the weights of the bag are his work.
A just weight (rather, scale-literally, the upright iron in scales which the weigher holds in his hand, and in which the tongue moves) and balance are the Lord's: all the weights (literally, stones) of the bag are his work. Just weights are according to His will and ordinance. Merchants were wont to carry weights in a bag for weighing their wares, (Deuteronomy 25:13, etc.) As they are instituted by Him who implants the sense of justice in man, and the wisdom whereby men contrived this method of testing honesty, so they are approved by Him, end are pleasing to Him. So the pagan poet Hesiod says-`God gave justice to men' [anthroopois de edooke dikeen].
