שמואל א, פרק כ׳, פסוק ג׳

Faced with his closest friend's disbelief, David must explain the harsh reality of the king's true intentions. Jonathan assumes that because his father usually shares his plans, his silence means there is no plot against David. However, the king's silence is calculated. Saul has already made a firm, unyielding decision to end David's life, leaving no room for doubt or any need for consultation [מלבי״ם]. Furthermore, the king is acutely aware of the deep affection Jonathan holds for David. To spare his son from immediate sadness, Saul deliberately conceals his deadly plans.

To impress upon Jonathan the gravity of the situation, David swears an oath, stressing that he lives under a constant, looming threat of death [מצודת דוד, ביאור שטיינזלץ]. He explains that the boundary between his life and his end is incredibly thin, amounting to no more than a single, tiny step. The primary approach among commentators connects this vivid image directly to the terrifying moment when David played music for the king, and Saul hurled a spear at him. In that split second, had David not shifted away by just one step, the weapon would have struck him dead. This harrowing experience serves as undeniable proof to Jonathan that the king's resolve is absolute, and David remains in perpetual danger regardless of whether the king acts with clear intent or not.

While the physical distance of a single step highlights the immediate danger, another perspective connects this concept of crossing a line to the actions of David's wife, Michal, who previously helped him escape the king. From this viewpoint, her decision to subvert her father's wishes is not viewed as a rebellion or a transgression. Because the king was pursuing an unjust and forbidden act, Michal's defiance was entirely justified. The duty to honor a parent simply does not apply when they demand something unlawful [חומת אנך].
