The Sharia of Moses in the TORA
Part 2 - The 365 Prohibitions of the Tora
272 - KEEPING FALSE WEIGHTS AND MEASUREMENTS
By this prohibition, it is forbidden to keep false weights and measures in our homes, even though we do not use them for purposes of trade.
The underlying idea of this commandment is cogently expressed by Rabbi Obadiah ben Jacob Sforno, sixteenth century exegete and philosopher, in his commentary on the Bible: “God abhors not only the actual practice of dishonesty, but also the instruments that enable one to commit it.”
