Adultery

Adultery is referenced here as the gravest stain on David's record, the sin that makes his righteousness claim require careful interpretation — he fell hard, but he never walked away from God.

Adultery is addressed directly here — the law prescribes death for both parties in a case of a man sleeping with another man's wife, underscoring that both bore equal moral accountability.

Adultery appears in the list as the second of the five social commandments, placed between murder and theft to show its gravity as a covenant violation — private but deeply destructive to the communal fabric.
