דברים, פרק ה׳, פסוק י״ז

The most severe prohibitions governing human relationships are grouped together to form the fundamental defense line of society. By bundling the protection of life, family, property, and the justice system, the text emphasizes that a healthy, functioning community cannot exist without mutual trust and personal security.

A subtle but profound difference emerges here compared to the first time these commandments were given: each prohibition is now linked by a conjunction. Practically, the original declarations were spoken by God in a single, continuous utterance, whereas here, Moses, a human being, repeats them and requires pauses between each concept [שפתי כהן]. Historically, this linkage serves as a reminder of the sin of the Golden Calf, where the nation stumbled in these exact moral arenas [פני דוד]. However, the primary approach among commentators is that connecting these prohibitions teaches how one offense inevitably drags another in its wake. A person who covets a neighbor's wife can easily be driven to murder if the husband stands in the way, and a thief will ultimately testify falsely to cover up the crime [קיצור בעל הטורים, שפתי חכמים]. Binding these social crimes together reveals that God examines not just the final criminal act, but the entire chain of thought and intention that led to it. As the Israelites prepare to enter the Land of Israel and disperse across it, they are reminded that a human justice system alone is insufficient; true societal stability requires the fear of Heaven and internal moral discipline [רש״ר הירש].

Regarding the prohibition against adultery, the specific terminology used refers strictly to relations with a married woman, rather than general promiscuity [רש״י, ביאור שטיינזלץ]. This precise definition is reinforced by its immediate connection to the prohibition of murder. Just as murder is a capital crime, this specific form of adultery carries the severe penalty of death imposed by the court [לבוש האורה, משכיל לדוד].

Finally, when addressing perjury, the text shifts from forbidding a false witness to forbidding a vain or baseless witness. The concept of a baseless witness is much broader. While a false witness offers fabricated testimony designed to wrongly convict or acquit someone, causing direct harm, a baseless witness violates the absolute standard of truth even when no financial or legal damage occurs [הכתב והקבלה]. This includes situations where the testimony is legally meaningless. For example, testifying about a financial promise made without an official act of acquisition is considered baseless, as the court cannot enforce it [רמב״ן, הטור הארוך, ביאור יש״ר]. It also encompasses offering testimony that the court is fundamentally unable to accept, such as a person testifying entirely alone, or witnesses who failed to warn the perpetrator before the crime. Because such testimony serves no legal purpose, it amounts to nothing more than destructive gossip and slander [העמק דבר, חזקוני]. Ultimately, this specific phrasing highlights the malicious intent of the witness, serving as a stark warning that invalid testimony undermines the very foundations of societal trust and can easily lead to legalized bloodshed [רש״ר הירש, ביאור שטיינזלץ].
