דברים, פרק ה׳, פסוק י״ח

The final mandate of the Ten Commandments penetrates deep into the internal world, demanding absolute control over thoughts and emotions regarding the family and property of others. It serves as a capstone to the preceding laws, rooted in the understanding that refining the heart and straightening the mind are the very foundations upon which all Commandments rest.

In earlier records of the Commandments, the home was listed before the wife. The shift to placing the wife first reflects the reality that the human drive toward women is far more powerful and difficult to master than the desire for wealth [הטור הארוך, רמב״ן]. This sequence also mirrors the natural progression of human life. A young man naturally desires a wife first, and only later seeks a house and property. The earlier arrangement, by contrast, was structured around logic and wisdom, which dictate that a person should ideally secure a home before marrying [חזקוני, ביאור יש״ר].

The instruction employs two distinct concepts regarding longing for what belongs to another. While some commentators argue that these concepts are essentially identical, simply expressing the longing of the heart [רש״י, ברכת אשר בשם הסמ״ג], the primary approach among commentators points to a fundamental difference between thought and action. The prohibition against desiring addresses the heart alone. A person violates this simply by thinking and planning how to acquire another's possession, even if fear of authority or personal weakness prevents them from carrying out the plan [אבן עזרא, רמב״ן, רלב״ג]. Conversely, coveting refers to the practical stage where a person actively tries to obtain the object, such as by pressuring the owner or begging repeatedly until they are forced to sell [רלב״ג, ביאור יש״ר]. The specific ban on internal desire was emphasized to uproot sin at its source, since unchecked desire leads to active coveting, which can ultimately result in theft or assault [רבנו בחיי, ביאור יש״ר]. This perspective firmly rejects the misconception that people are not held accountable for their thoughts, emphasizing that a pure heart is the ultimate purpose of the Commandments [אבן עזרא].

Another distinction between these concepts lies in the nature of the object in question. Coveting is associated with things possessing an intrinsic beauty and perfection that everyone recognizes, which is why it is applied to a wife. Desiring, however, relates to items that lack inherent perfection and only hold value based on their usefulness to a specific person, such as tools or assets. God forbade desiring these functional items to prevent a person from longing for another's property, even if they convince themselves that they have a greater need for it than the rightful owner [הכתב והקבלה]. Regarding a married woman, there is an additional, severe restriction against even enjoying the sight of her, regardless of whether a person has any intention or ability to take her, a restriction that does not apply to inanimate property [העמק דבר]. Furthermore, placing this command immediately after the prohibition against false testimony serves as a stark warning: a person must not covet another's wife and then testify falsely against the husband to cause his execution in order to marry his widow [קיצור בעל הטורים].

The detailed list of protected property includes a field, an item absent from earlier accounts. This addition reflects the immediate historical context, as the Israelites were standing at the threshold of the Land of Israel, where they would soon own agricultural land [קיצור בעל הטורים]. From a legal perspective, the field serves as a defining category. Just as a field is a definitive asset that is bought and sold, the prohibition against desiring applies to absolutely anything that can be transferred or purchased, whether real estate or movable goods [הטור הארוך, רמב״ן, ביאור יש״ר].
