DEUT1467 With regard to [weights and] measures … they are explicitly referred to [this verse]: "For anyone who does these things [false weights and measurements - AJL] , it is an abomination [before] the Eternal, your God"; and the Sages of blessed memory have said (Bava Basra 88b): "The punishment for [false - AJL] measurements is [even] more severe than the punishment for promiscuity.… "And they have said (ibid. 88a): "A wholesaler cleans his scales every thirty days." Why is this so? So that the scales do not lose their accuracy through inattention – and [in doing so] he avoids punishment.
