A person must conduct a court of honesty and always strive for the middle line. All the laws of the Torah are designed to construct it.
A woman between two men, one of whom has died and the other is alive, or they both are alive, but one is her husband and another is not, or two weights, large and small, and so on, all of it is the construction of the middle line in all its forms.
The Torah gives basic principles on the inanimate, vegetative, animate, and human levels on how to maintain the middle line and how to carry it on. The conquest of the land of Israel means controlling the desire in the middle line.
Therefore, it is written: “You shall not keep in your pouch two different weights, one large and one small.” After all, you must carry on all your changes according to one principle—by the middle line.
