Encourage all your virtuous dispositions, and exercise them whenever an opportunity arises, being assured that they will gain strength by exercise, as a limb of the body does, and that exercise will make them habitual. — Thomas Jefferson
With forty-four distinct paragraphs and seventy-four commandments (27 prescriptive, 47 proscriptive) perashat Ki Tetse is filled with detailed instructions and guidance for living in covenant with G-d. Several times in the book of Debarim, Moshe tells us that the mitsvot are for our benefit, leading to growth and a connection with the Almighty. He teaches us to lead lives that are not just moral and ethical, but holy.
For God your Lord walks about amid your camp…so the camp is to be holy. (23:15)
The potpourri of mitsvot in Ki Tetse is varied, ranging from lost property, safety precautions, clothing, sexual behaviour and relationships, borrowing and lending, charity and international relations. Towards the end of the parasha, we find one of the more obscure commandments, the prohibition against possessing weights and measures that are flawed and off-sized.
You are not to have in your purse a stone-weight large or small. You are not to have in your house a measure both large and small. A perfect and equal stone-weight shall you have….(25:13-15)
It is quite understandable that the Torah forbids using such tools, but what is so wrong with possessing them?
Harbouring these flawed weights and measures maintains an open door to using them. While we would not necessarily consider a person immoral unless they actually used the tools, if we were to find such devices in one’s possession we might question their need for them. Unless a person has a use for such things there would be little reason to own them subsequently causing suspicion and concern.
Although this mitsvah is quite particular it hints to a valuable principle. In Hebrew our attributes and elements of character are called middot, literally meaning ‘measures’. They are called this because it is with them that we fashion our personalities and identities. Our aim is to have ‘measures’, or attributes, that are whole and fair rather than flawed and corrupt. Even if they do not lead to negative behaviours, the deficient attributes themselves must not be maintained. Possessing them alone sets us up for failure.
One should not say that Teshuba (return to righteousness) is only from transgressions that involve actions like promiscuity and theft; just as one must return from these so to must he examine the ill-attributes that he possesses and return from them. From anger, malice, jealousy, rivalry, frivolity, and the pursuit of money and honour…these are more difficult [to abandon] than those that involve actions…. (Rambam)
Addressing our deeds is an essential aspect of perfecting our character. However if we wish to strive not only for refined actions, but refined souls, we must consider both what we do and who we are. This is a rigorous and serious task which requires considerable effort and diligence on our part. If we are successful in achieving it, we create internal purity and allow God’s presence to rest within.
