מלכים א, פרק א׳, פסוק נ״ב

Solomon offers a path to redemption, placing the fate of a defeated rival entirely in his own hands. He grants Adonijah an opportunity for a clean slate, but this pardon is strictly conditional. The core requirement is that Adonijah must prove himself worthy. The primary approach among commentators is that this demands practical loyalty: Adonijah must accept the new royal authority, behave properly, and serve the king with the same obedience as any other minister or servant [מצודת דוד, רלב״ג, ביאור שטיינזלץ]. However, another perspective suggests this requirement is deeply internal and moral, meaning he must become a person who fears sin and possesses the inner strength to conquer his impulses [רד״ק].

If Adonijah meets this standard, Solomon guarantees his complete safety, assuring him that he will face no penalty for his past actions. This guarantee is expressed in everyday human terms through an intentional exaggeration, emphasizing that he will not receive even the slightest punishment, keeping him completely unharmed down to the hair on his head [מצודת דוד, מצודת ציון]. Notably, Solomon does not seal this promise with an oath; he simply establishes a firm reality that depends entirely on Adonijah's future choices [מלבי״ם].

The alternative, however, is absolute. Should any evil be found in Adonijah, the consequences will be fatal. This evil refers to any future sign of rebellion or failure to fully accept Solomon's rule [ביאור שטיינזלץ]. If he crosses this line, his protected status will instantly vanish. He will become retroactively liable for his original uprising, meaning that even if his new offense is minor and would not normally warrant a death sentence on its own, the combination of his past and present actions will result in his execution [מצודת דוד, מלבי״ם].
