Leviticus 19:36 "Honest balance, honest weights, an honest dry measure and an honest liquid measure, you shall have"

The next time you go to the fruit and vegetable store, take a look at how the owner weighs your bags at the counter. You'll notice that his cash register figures out your bill by multiplying the weight of your bag by the price per pound.

Did you know that the register must be periodically checked for malfunction? After all, it's only a machine!

Imagine its scale becoming unbalanced. You might end up paying more for your bag of fruit than it is worth because the scale is not weighing the fruit properly.

The Torah commands us to ensure the use of exact measuring units, to make sure we deal honestly with each other.
