A righteous person's peace of mind is truly tested during moments of crisis and uncertainty. While those who act wickedly often live in a state of constant fear, a person of deep faith possesses an inner resilience that serves as a shield against panic.
When alarming news arrives, it can take various forms. The primary approach among commentators notes that this might involve broad tragedies, such as disasters striking the world, the nation, or the state [אבן עזרא, מצודת דוד, מאירי]. On a more personal level, the threat could be rumors of jealous enemies plotting harm, or worrying updates regarding distant relatives and children [רד״ק, מאירי]. A classic example of maintaining composure in the face of alarming news is the story of Hillel the Elder. While traveling, he heard a cry of distress from the city but remained completely calm, declaring with absolute certainty that the scream did not come from his own home [תורה תמימה].
This remarkable absence of fear stems directly from living with clean hands. Anxiety is frequently a symptom of a guilty conscience burdened by past wrongs, but a righteous individual, free from such sins, simply does not experience this dread [אלשיך]. Generally, people are afraid for two main reasons: they either fear revenge from those they have harmed, or they dread the unpredictable strikes of blind fate. A righteous person has no reason to fear human revenge because his actions are honest, and he does not fear random fate because he relies entirely on God's ability to turn circumstances in his favor [מלבי״ם].
This mental state is one of profound stability. The heart is settled, focused [ביאור שטיינזלץ], and deeply faithful to its Creator [רש״י]. It stands firm on its own, anchored by inner goodness [מלבי״ם]. Consequently, this trust is placed exclusively in God, rather than in physical security like vast wealth, military strength, or social connections [רד״ק]. There is a complete reliance that God will provide protection and keep harm at bay [מצודת דוד].
Ultimately, this relationship is mutual and inseparable. A person does not fear terrible news because his heart is steady and trusts in God, and the very existence of that steady trust is exactly what guarantees no bad news will ever shatter his peace [תורה תמימה].
